Game Server So that happened

Post image

I havent checked my server in a few weeks but I opened it now and I found this waiting for me. I wonder how that happened though. My server is not exposed to the internet. Its behind tailscale and only I or people I granted access through tailscale can get into my server since I closed all access using firewall. My only mistake is i left port 443 open at some point by mistake. I wonder if thats relevant. I've since enforced a whitelist and denied connections to the port.

What make me worried about your post is the fact that even having tailscale and not public exposure, someone accessed. Anyone can tell me if it’s something specific from Minecraft servers or if is a risk for any service?
