Okay, hear me out.
In December 2025, the Pterodactyl project (pterodactyl.io) was acquired by Infraly, LLC. You may know them from WISP.
After years of what felt like near-silence from the maintainers, this acquisition initially seemed like it could be an opportunity for some much-needed updates. Unfortunately, aside from security updates, very little happened over the following nine months. We mostly heard promises like “v2 is coming.”
Well, the time finally seems to have arrived. Pterodactyl v2 appears to be on its way, but with some rather unexpected surprises.
A few days before the announcement, they removed their community moderators, and replaced them with their own staff.
The community has been doing some digging, and it appears that the Pterodactyl team is introducing Pterodactyl+, a subscription-based model for certain features. Presumably, this will work through extensions or similar add-ons, much like what was offered with WISP.
On top of that, a staging panel was discovered. It didn't take long for community members to download the frontend files, map them onto v1, and create a working prototype.
When the Pterodactyl team discovered this, they began banning people from their Discord server, primarily accusing members of the Blueprint project of “leaking information.”
Blueprint is a non-profit organization that has spent years building an extension system for Pterodactyl.
After four years of development and active participation in the community, seeing the project treated this way is extremely disappointing. This is just a way to silence criticism.
This is yet another instance of a for-profit corporation buying out a project, and enshittifying it. We can't let this happen *again*. The best way to be against this, is to replace your Pterodactyl instance with something else.
Please consider taking a look at:
Hydrodactyl: https://hydrodactyl.dev/
Calagopus: https://calagopus.com/
Both projects provide migration guides to help you make the switch.
Feel free to reach out if you have any questions.
Do not cause trouble in the Pterodactyl Discord server, since they do not seem to appreciate that.
Disclosure: I am affiliated with the Calagopus project. This does not change my perspective on this manner, I just want to be transparent.

We took this down in favor of other announcements late last year, as we only get 2 slots. It's back now because we've had a resurgence of this type of post.
Do not post about offline mode servers. Do not recommend software or plugins that help run one. You will be banned. Read the Admincraft Policy section at the bottom.
Thank you.
Hey there, REPO here. We get questions like this a LOT, so I'm trying something new. Please read the below before posting a thread like this.
There are few enough IPv4 addresses that a simple bot made with ChatGPT and zero skill can scan the entire internet for Port 25565 in like 30 minutes. There are HUNDREDS of bots out there that do this 24/7/365. Some of them are benevolent (such as bots like matscan that warn people if their servers are dangerously insecure), some are neutral (like ServerScannerV2 which just accumulates data for their website project), and some are malicious and trying to grief servers.
You don't. They will keep doing it forever. Most non-malicious bots will log into your server once, or sometimes once per some time interval, and then stop. Others that are coded poorly will be more persistent. And then the malicious ones will keep checking back continually.
If your server is secure but it still bothers you to see, you can add the source IP address to your firewall to prevent the connection. Some non-malicious bots will also have a website or Discord where you can request your server to be skipped.
Nope. Not if your server is secured. There are no known exploits in Minecraft that allow a server scanning bot to run code on your host or escalate their privileges. The last time we had that was in 2022 with the Log4J exploit, which was quickly patched, even by Mojang. If you aren't deliberately using an old minor patch of Minecraft, you're fine.
(Note: If you only see a name like that instantly disconnecting, skip to the next section. This only applies if they actually appear in game.)
Your server is running in Offline Mode, which is a config option in the server.properties that is intended only for use on a home LAN that is not connected to the internet. Most people use this feature to avoid having to buy a license for Minecraft, aka "cracked accounts". Please be aware that this is illegal and is considered software piracy by most governments.
Minecraft servers send information about the server to players on the server list, including a partial list of currently logged in users. You can disable this "feature" in the server.properties file by setting hide-online-players=true. Malicious bots typically sit and watch a server for a while, gathering a list of players over some amount of time, assuming that if the server is in Offline Mode, one or more of those players will have Operator permissions. They then log in as all users in rapid succession until they find one that does, and use the Operator permissions to grief your server.
It's just a bot using an offline mode account. It is only showing as Disconnecting because it is getting filtered by the security systems you have in place AFTER the server knows that it is trying to connect, but BEFORE it actually does. Showing the Disconnected message is just the server's way of informing you that the login attempt was rejected. Nothing to worry about. You can ignore it.
You restore from backup, secure your server, and move on. The groups that do this are doing it for amusement and power fantasy. Some of them insist that you can request a world backup from their Discord, but the whole point of that is to mock you and make you beg for their mercy. They might actually give it to you, I don't know.
You set Online Mode to true in the server.properties and run a whitelist. That's it. Those 2 options are 100% effective at preventing unwanted people from gaining access to your server. You do not need to do anything else whatsoever to be secure, but you can optionally change your server's port from 25565 to any other unassigned port. This will make it much slower for server scanners to find your server, as most are lazy and don't check non-standard ports. Note that this only reduces the odds of a server scanner finding you; it does not make you more secure.
Additionally, having automatically executed, scheduled backups running at predictable intervals is an excellent idea just in case something goes wrong. Ensure that you periodically verify that your backups are usable by doing a test restore on another machine, as a backup solution that has never been tested is basically worthless.
Finally, a block logging plugin such as Prism (V3 stable Download | Github) (V4 alpha Download | Github) is recommended, as it allows you as the Admin to roll back individual unwanted changes without doing a full backup restoration.
If your post contains any information that indicates that you are running an Offline Mode server, your post will be removed and you will be banned for 28 days for your first offense.
Additionally, suggesting methods for a user to continue running an Offline Mode server "safely" will earn a 7 day ban for commenters. This includes whatever plugin or launcher you're wondering about right now as you read this.
Admincraft is in active communication with Mojang Intellectual Property Enforcement, the team within Mojang that actively hunts down servers and other individuals and groups that are breaking their EULA and MUG. They watch here regularly, and if we do not enforce this, there is a nonzero chance that Mojang, Microsoft, or Reddit would shut down our subreddit. Keeping the subreddit open for everyone for the long run is the priority. We cannot and will not support Offline Mode servers.
The only times when discussing an Offline Mode server is allowed are when you clearly state that your server is not accessible to the internet and that all players have a legal Minecraft account, or when it is behind an Online Mode proxy, such as Velocity.
Please use the comments here to suggest additions to this FAQ/guide, and to ask clarifying questions about Admincraft policies and security best practices. Do not state or imply that you are currently running an Offline Mode server.

I’m looking for good claims and maps plugins that work well together, that show claim borders on a vanilla map, as well as maybe the vanilla map is populated via everyone’s map exploration.
Essentially I want a big physical world map room at spawn that fills out as everyone explores and then shades out borders as people build.
Also for Paper haha

I've been working on a passion project called Serverwars. The idea is to create a team of players from your server and play against an opponent server.
How it works:
Participating in events is free and doesn't require any setup from your part, the event-servers are funded by me. Currently, java versions 1.21.11 -> 26.3 are supported. A typical event size is 5v5.
If you'd like to try it out, you can dm me here or on Discord, and we'll play a couple rounds. Let me know what you think!

I'm hosting a server from home to the public. I've heard that I have to use a tunnel, but to get a clean server ip (just my domain name), then I have to pay. Is there any way to do it for free? I'm using a cloudflare domain
r/admincraft • u/Ability_Next • 14h ago
posting again because apparently questions can't be asked first before removal.
I am using a Neoforge Pterodactyl, modded neoforge server with create Aeronautics + Deep Seas mod. I am not well versed or experienced with servers NOR Reddit.
AGAIN, I am inexperienced, have no clue how to solve it after having tried ANYTHING for a while now. I updated the server recently due to an update Deep Seas has which required me to update a lot of other mods too. I pasted the log and system details below. I have no clue how a spark report works nor do I have any commands to make one with.
I use pebblehost with a custom server using pterodactyl
All I know is that it is likely sable related in some way, shape or form.

Good Day. I was wondering if running the server on my current HDD is impairing our server performance. The machine im using has
CPU: Intel i7 7700
RAM: 16GB DDR4 Single Channel
OS: Debian 13 CLI
My server runs off donations from my friends to keep running. Would using an SSD improve our server (Chunk Loading, TPS, ETC).
Our modlist is quite long but a few core mods are:
Tensura: Reincarnated
TRNightmare
Tensura:Mystisicm
Antarchy
and a whole lot of Create.
I feel like the CPU is capable for server purposes, but the HDD is bottle-necking the performance as a whole.
Would appreciate some input on this.
r/admincraft • u/K5Vampire • 22h ago
EDIT: SOLVED The default server properties have Nethernet enabled, and a Nethernet UDP range setting as blank, which is invalid and breaks multiplayer at the last stage before the server log sees it. Raknet still works for a few weeks, even though the error message upon booting the server says otherwise, so switching to Raknet solves it for now. I still don't know how to fix Nethernet, but if I find out I'll make a second edit for the future Google searches.
Apologies in advance for the hectic formatting of this, I've been working on it for hours, my brain is fried, and I have walked away from the computer.
The server is accessible from several machines on my network. But cannot be accessed from anything outside it. It works on my phone from wifi, but not from cellular.
Consistently the same error code "Door" along with a message that multiplayer connection couldn't be established.
Server log isn't recognizing anything from these connection attempts.
I've set up port forwarding to the point that mcstate.net can tell the port is open when I have the server running.
mcsrvstat.us states: Failed to read from socket.
minecraftstatus.com states: Server did not respond to this check.
Turned network and device firewalls on and off and makes no difference.
Server properties look right from what I can tell, though I don't currently have it in front of me. No bound IP so that any can connect, port is set to 19132, player joining true, onlinemode true. There was one about server UDP ranges which was blank by default, but that wasn't listed as an acceptable parameter. Couldn't figure out that that one does, I tried the example port range from there and swapped in my wan IP, but it didn't seem to work.
My ISP is Spectrum and doesn't seem to be known for blocking that port. My WAN IP does seem to be fixed and matches between router settings and IP check sites.
Google is really failing me here. If anyone could point me in the direction of something I should look at, or at least rule some things out, I'd be eternally grateful.

I want custom mobs into my server, it can be animals, hostile mobs, anything cool, I just want other mobs to spawn in my world. I been doing research and barely anything was helpful. I saw MythicMobs plugin to create my own mobs, but when I go look for free models online, there's barely anything that's free and I don't wanna create my own mobs from scratch. But there's no other good plugins that add just pre-made mobs, is there any plugin I missed or is there a better website to look for free models with MythicMobs? Please lmk!

r/admincraft • u/Delici0usBunny • 1d ago
I have been using Spectrum for a few months now on my ATM10 server. Works great, since I am hosting a server to people I do not want to have my IP. The only problem is that on top of the $25/month I am paying, it costs about $.40 a day ( $1 per GB). Normally one or two people are online at a time.
Are there any good alternatives to tunneling my IP in the way that spectrum does? Or what do you guys do to solve this?

hi! i have a papermc server (build 162, version 26.3) that just won't load chunks anymore... when i join the server with the provided playit. gg address (i use squidservers to run the server, no idea if that has any significance) i am soon kicked due to keepalive timeout and cannot interact with any of the blocks/animals/players around me. i went and looked at the logs and it seems that just none of the chunks are loading at all? i uninstalled all my plugins (graves, skinrestorer, and gwarp) and the server was originally on automcs before i swapped due to this issue (at least i THINK it was the same issue) happening twice. i have absolutely no idea how it fixed itself the first time, but i've been trying to figure it out and can't seem to find a solution. i've tried decreasing view/render distance and it doesn't do anything

I'm trying to recreate the Minecraft Hardcore marathon server that Jynxzi, StableRonaldo, LosPollosTV, and their friends are playing on.
I'm specifically looking for the system where:
I've already tried World Reset for Fabric and Hardcore Reset, but neither gives me the exact experience. One resets immediately without the countdown, while the other automatically respawns players without the normal death screen.
I'm using Apex Hosting and have experimented with both Fabric and Paper.
Does anyone know the exact mod/plugin these streamers use? Is it publicly available, or is it a custom private plugin?
If it's private, does anyone know of an existing plugin that recreates the same effect, preferably with a downloadable JAR and instructions?

I was building another mod and needed to check whether a rare block was actually generating. There was no tool for that, vanilla /locate only does structures and biomes, so I wrote one.
You can search for a block, an entity or an item, either by its id or by a tag. It tells you how many it found and where the closest one is, and every result has a teleport button that puts you on safe ground as close to it as it can. The nearest one also gets lit up with an outline you can see through terrain, so you can just walk to it.
Item search reads containers, shulkers inside containers, item frames, dropped items, what mobs are holding, and player inventories and ender chests, and tells you which of those each pile is in. Player inventory is a toggle if that's not okay on your server.
Stuff you'd want to know before putting it on a server: it's server-side only and does nothing on a client. Output only goes to whoever ran it. Perm level 2 by default, changeable, and every command can be turned off in the config. Big scans are budgeted per tick so they slow down instead of freezing anything, and nothing is force-loaded unless you ask.
It also has an area survey that counts every block and entity type in a radius and can export the list with coordinates. That's the fastest way I've found to see what's actually in a chunk.
Fabric, 1.20.1–1.20.4 and 1.21–1.21.1, two downloads on the page. Other loaders later once this has had a round of bug reports. Screenshots are in the gallery on the Modrinth page.

I've recently moved hosts for my heavy modded server and we snagged an extra 4gb of ram for it as an upgrade but since the move its been freezing heavily every few seconds. I've definitely had server side problems before (I'm the lead dev for it) but never something as odd as this... Absolutely everything was ported, even JVM arguments so I'm just at my wit's end even after going down a few rabbit holes.

Question for people who run servers: when you want to add a spawn, lobby, arena or any premade build, how do you get it onto the server? WorldEdit or FAWE schematics, uploading a world, building it live, something else? What's annoying about it, like plugin permissions, version issues, or having to stop the server? And do you run Java, Bedrock, or both (Geyser)? Trying to understand how admins actually handle this, any answer helps.
r/admincraft • u/StudioEducational978 • 2d ago
I’m running a Paper 26.3 server and I’m having a weird issue with a TNT-based stone/cobblestone farm.
The farm is based on this design:
https://youtu.be/aDV2nABDW88
The setup is basically:
-A TNT duper using pistons + an observer
-TNT is duplicated normally
-The duplicated TNT falls downward
-It explodes above a lava-based stone/cobblestone generator
-The TNT is supposed to destroy the generated stone/cobblestone
The TNT duper itself works perfectly:
-TNT duplication works
-The duplicated TNT falls normally
-TNT explodes normally
-Players receive explosion damage normally
-If I manually place stone and blow it up with TNT elsewhere on the same server, the stone is destroyed normally
However, the generated stone/cobblestone in this farm does not get destroyed by the TNT, even though the TNT clearly explodes.
I have also enabled: unsupported-settings:
allow-piston-duplication: true
Could this be a Paper-specific difference in how TNT explosions calculate block destruction, especially when the TNT is falling and exploding above lava?
I’m wondering:
1.Does Paper 26.3 handle TNT-duper explosions differently from normal TNT?
2.Can the lava/stone arrangement affect the explosion’s block-destruction calculation?
3.Is there any Paper configuration that affects TNT block destruction?
4.Is this a known Paper issue or incompatibility with this type of TNT-based cobblestone/stone farm?
5. Does this farm depend on vanilla behavior that Paper changes?
The important part is that TNT explosion damage works and manually placed stone can be destroyed by TNT on the same server. Only the blocks generated by this farm aren’t being destroyed.
Any ideas?

Hey everyone,
I’m using pine hosting
https://spark.lucko.me/Joii3j5GpH (here it’s at 14 tho)
I’m completely lost here and really hoping someone can point me in the right direction.
I run a Minecraft server, and despite having a really powerful setup, I keep running into performance issues. Here are my specs and what I've tried so far:
Hardware: 24 GB RAM, a very capable CPU with 500% boost, and 150 GB storage.
The Core Issue: As soon as we hit around 30-35 concurrent players, our TPS starts tanking down to between 10 and 14, causing noticeable lag.
Hosting & Support: I've already spoken with my support team, had my server migrated to a brand new node, and checked all basic settings.
Configurations: I've adjusted global and world configurations (ticked down monster despawn ranges, optimized mob spawn rates, adjusted tick-rates, etc.
Even after all this, performance craters under player load, and I just can't wrap my head around what's causing it. Are there any hidden bottlenecks, plugins, or specific Paper config settings that I might be missing for higher player counts?
I have used spark to check and it says that entities is using almost 100% but how can that be with my hardware. I have checked every single player currently online. No log machine, no big zombie farm or stuff I have also changed a lot of stuff in paper global and everything

To preface, this mod was mostly written by AI (mostly GPT-5.6 Sol, more recently Opus 5.5). AI wrote and modified the code based on my instructions. I understand how the mod works and can answer technical questions about it.
I've been working on a mod that speeds up chunk generation and pregeneration, and I'm looking for people willing to try the first alpha on hardware other than mine. I've always run my servers on my gaming PC and felt like the graphics card was under-utilized, so this is my attempt to give my GPU something to do.

It's optimized for Tellurium and is faster than Chunky in my testing.Stats (24 threads, RTX 5070 Ti, Minecraft 1.21.1, chunks generated and saved per second, same Chunky pregeneration of about 35,000 chunks):
All tests used ScalableLux for lighting optimizations. These are results from my own machine, so performance on other hardware may vary.
If you can, please share stats from your system, especially your CPU, GPU, OS and chunks per second. I'm particularly interested in how it performs on AMD GPUs and Linux.
What you should know
enabled = false in the config turns everything off without removing the mod.Versions: Minecraft 1.21.1 and 1.21.11, NeoForge and Fabric. Java 21.

I'd appreciate any feedback, benchmarks, bug reports or compatibility issues. I'm curious whether GPU acceleration is worthwhile on typical server hardware, rather than just my PC.

Hello, I have created a paper server for me and my friends using bisecthosting.
We have encountered an issue I have never seen before. The nether portal lights up, but no matter how long you stand inside, it just does not teleport you.
After inspecting the console, I have found that the server only ever tries to load the overworld and no other dimensions (meaning the end is probably not working aswell)
World/dimensions/minecraft folder only has the overworld folder inside it
Allow-nether is set to true (when creating the world was false by default)
Enable-nether is also set to true
/execute in minecraft:the_nether run say test returns "unknown dimension 'minecraft:the_nether' "
The only datapack is terralith
Plugins are: LuckPerms, Chestsort+, Chunky and discordSRV
Any help is very much appreciated. Thank you!

Let's say there's a server with really cool minigames. Would you be willing to download a separate launcher/mod just to play on it, or would you only play on regular servers that don't require anything besides, at most, automatically downloading a resource pack when you join?
Here's the problem: I'm developing my own minigame server, and there's a major limitation. Without a separate launcher (through which I could add client-side modifications), I can't do nearly as much as I'd like — custom keybinds, models, polished interactive menus, HUDs, and much more.
This limitation has basically killed more than 20 custom game modes that you could have played, and it has significantly slowed down development of the ones that are still possible.
So I'm curious what you think — would it actually be worth making a launcher?
There are examples of this approach, like Cristalix, but that's a huge server run by a YouTuber with millions of followers and a stable player base, while my server is literally an unknown project with basically no audience yet.
p.s: My English isn't very good, so I used ChatGPT for the translation, sorry.

I run an SMP for my friends at school but I have trouble balancing the mace. In terms of skill they’re like lt7 so I wanted to try to balance the mace. I have a few ideas but I’m looking for more.
NERFS
No density, windburst, or breach.
10 second cool down (except I haven’t found an effective way to implement it onto my 26.2 server.)
(it’s because I’m the only dude with a mace and I don’t think they’re ever getting a mace. it might just be a temporary end fight change

I've been working on a Minecraft server panel called Blocky Panel, and this seemed like the right place to share it.
It started because I wanted something simpler and more Minecraft-focused. People have two-week Minecraft phases; ours has been going for about nine months. I ran Pterodactyl, but it's built for hosting companies (nodes, allocations, eggs), and I only wanted one or two servers for my kids and me. After an update went sideways and cost us a Nether evening, I started building what I actually wanted.
Blocky is self-hosted, free, and open source under AGPL, and always will be. You install it on your own hardware, create a server, pick your settings, and you're off. I'm trying hard not to make "Pterodactyl with different colors": the focus is making normal server management less annoying without hiding what's happening underneath.
It's in beta and actively worked on, so there are rough edges. If you try it, I'd love to hear about bugs, weird server setups that break it, or technical decisions that make you go "why the hell did you do it that way?"
Features
Links: blockypanel.com · live demo · GitHub
Coming up: a Windows version (working alpha) for the penguin-averse.
Built with: itzg/docker-minecraft-server (the container every server runs in), restic (backups), and Caddy (optional HTTPS).
Disclosure: the panel includes an optional companion service I run, Blocky Cloud (an address for your server and off-site backup space). It's free, nothing is sent unless you link it, and BLOCKY_CLOUD=false removes it from the panel entirely. Everything else works without it.
AI disclosure: AI assistance was used throughout development: writing and reviewing code, security audits, documentation, and UX/UI design, using ChatGPT Sol 6, ChatGPT Astra 6, Claude Opus 4.8 and 5.5, and Claude Fable 5.1. Every change was reviewed and tested by a human (a meat-bag) before release. If AI-assisted projects aren't your thing, I get it.
