Unable to Join my own Server
Im using the prism launcher to play a fabric server and havent modified the pack in any way. Im using the a java21 graalvm installation, and allocated 12 out of my 32gb of ram. The server has 20gb of ram and is an oracle server. I tried restarting+reinstalling the server and my version but no fix, and checked that both the client and server are running the same version but no fix. The only thing I could think of is that I didnt install fabric correctly as the last server instance I made was forg...

Reverse Proxy on home server issues
I have a decently powerful hardware just lying around my house, which I decided to put to good use. I used to run a Minecraft server by renting a VPS monthly, but it's basically a wallet drain. Since my internet lives behind the CGNAT of an uncooperative ISP (which offers VERY GOOD service btw, although no IPv6), I had to proxy via a VPS for my server to reach the internet.
What I did on the VPS:
- Installed and updated Ubuntu 24.04 LTS, along with nginx, and ssh.
- Enabled UFW and allowed the necessary ports, including 25565....
Last time since login.
Is there a way to see when a player has last logged in {or the last player to log in/log out} so that you can see which backups you can delete since you don't want to keep super old backups where players weren't even connected, Id like to keep backups where players have been active in the server.
I know about (https://www.spigotmc.org/resources/plan-player-analytics.32536/) but want to know if there is anything easier than that, I'm on pterodactyl paper....

Map built on server loads wrong only on server but works on singleplayer
I run a dedicated modded server on my own separate desktop machine and have been for the past 2 months building a modpack and server. The modpack is now in a stable version where I make no changes to it, but am now creating a map for the server experience which includes using all the mods included to decorate and build.
I have had no issues with the server, zero error logs that are relevant to this issue (ones that are from EasyNPC which is basically expected because of how it runs in a server environment and have seen these errors for months with no issue) Yesterday I shutdown the server to handle desktop updates and other sidework as I always have with the stop command in the terminal and then letting it handle the closing of all windows. When I booted on the server this evening and joined from my machine, the blocks had been replaced with different ones from when I left and was experiencing severe lag which has not been an issue at all for the last 3 weeks I have been connecting each day and playing for hours with multiple shutdowns and reboots.
I did some research online to make sure I wasn't missing anything basic and tried the following with no success....
Java or JavaScript?
I'm wanting to learn how to make plugins for my Java server, but I'm hearing conflicting results that I should learn Java, or that I should learn JavaScript. Which language do plugins actually use?
I'm already in the middle of learning HTML so I can kinda dip my toes into the whole world of coding, but after HTML I want to move on to Java or JS....
You cant login from this ip address
how can i fix this issue. i tried to solve it with the owner and on my own (i am a admin in the server) but i couldnt figure out how to solve the issue. I also googled it up and saw it had something to do with cmi (a plugin that we use on the server) but when i tried this i kept getting the same error.
(i tried using the /lockip (playername) thingy)

TPS loss but what is the exact cause?
So usually my server (Fabric 1.21) really only drops to 17 when loading a lot of chunks or entities, but is otherwise fine.
Now, my question isn't "what is causing my server to lag" but "why" is this causing my server to lag?
The culprit of the TPS drop is https://modrinth.com/datapack/witherswrath Wither's Wrath.

Is there a better way to view memory usage from Pterodactyl?
I'm running Purpur 1.20.4 and using aikars flags, with that being said, the flags are allocating almost all of the memory to the server so it shows I'm almost always maxxed.
I know I can view the ACTUAL usage with spark and /memory but is there a plugin/addon/script that can make that correlate with the Pterodactyl values so I can see it live without running a command?...
Looking for events / competition ideas

Problem with some hackers
sorry if this isn't the right place for this, im just out of ideas
So last night, a server I help run had multiple hackers (one who even advertised about it in their discord bio), we're a small community who doesn't want to really grow much more, but it appears that something happened, main notes about the attack, its was ~4 total people (though probably more, just this is who we found),
1st just griefed, and that was that (though going through the logs they appear to have posted a discord link, and presumably that's where all of them were)...

Problems with Garbage Collector and TPS Spikes
I'm unsure how to proceed about this
The server is lagging every few seconds due to the garbage collector, I have monitored trough the spark gcmonitor and the time checks.
Tried Aikar's flags, however, the Garbage Collector had an average frequency of about 25.5 hours > link
Returning to the most bare bones flags possible, incredibly the GC appeared to work more normally, but, lagging more frequently and intensively > link
