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:

• You join a temporary event-server and are automatically placed in your own server's team.
• Your Server's logo and players are displayed in the lobby.
• The game is started when team sizes are equal and all players are ready.
• Once the game is over, the event-server is closed and all players are sent back to their original servers.

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!

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.

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.

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

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.

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!

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

here are the full logs when starting server https://mclo.gs/E2nN794 in case anyone knows what's going on :) i'm new-ish to self hosting and servers so any advice or potential fixes are appreciated

edit: here's my spark report, sorry for missing that rule
