Invalid Packet size on Fabric Server

[burdoto]

i've seen theres a couple of "invalid packet size" kind of issues;
but none quite matches my issue behaviour;

i literally ALWAYS get the invalid packet size error, no matter the input

server is hosted on the same machine, password is good and rcon port is unique as well. theres only one server responding to this, but it just wont get better at all no matter what i set up

rcon ports are unique, no duplicates
please let me know what further info you need.

i am running archlinux
java version is 17
mcrcon is on 0.7.2-1

i just noticed when testing on another server that this does NOT apply for all servers; 1.20.1 fabric is the one that was affected

I'm also having this on my fabric server. However, it doesn't seem to be every message. Specifically, help seems to error with a packet size of 4106. Then the next command I run, always errors with some large number. However, if I don't run help first, it doesn't error on the other command, and executations after the first large error work as normal.

Just installed mcrcon on my server and I get this error when running help. I'm guessing the help command on a heavily modded server just has too much to send over rcon? Not sure if it's a Minecraft server limitation or this software.
