OPTIONAL: Which mods are affected?

This was tested with Moonlight Lib & Fast Paintings

I did not encounter any crashes/issues with painting rendering when it allowed me to connect to certain servers.

I've also been getting this issue when trying to connect to certain servers. Specifically, my main Velocity server.

Here is the log (though it doesn't really say much, yes this is the latest): https://mclo.gs/IPWeajS

I did a little testing (all on 1.20.1):
Vanilla server -> Can Connect
Paper server -> Can Connect
Paper server behind Velocity, with NO plugins on either end -> immediate disconnect

dlont use paper. Paper is for vanilla. Many issues in the past were caused by people using paper with mods.
If theres an issue its their issue but good luck on getting that fixed on their end

This is 1.20.4, not 1.20.1. 1.20.4-fabric (the label) doesn't exist!

oh thanks for pointing that out.

do you have kripton or packet fixer?
do you have every compat?

do you have kripton or packet fixer? do you have every compat?

Never used PacketFixer but I have tired without Krypton + Raknetify to no avail. Even tried without any mods and still could reproduce this issue. I.e., just Moonlight Lib + Fast Paintings.
