Cannot start server.

[michlbro]

mcsleepingserverstarter version: v1.11.2 (latest)
OS: Linux Server 6.1.0-28-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.119-1 (2024-11-22) x86_64 GNU/Linux
Minecraft version: NeoForge 1.20.1 47.1.106

Me and my friend are getting an error trying to join to start up the server with the latest version of this program. I have tried the pervious version of this and it works normally, however I was experiencing issues with that one where the port was never freed for minecraft to use when started up and hence never started up, so it crashes and tried to load up this program but the port is still not free, which is why I am trying the latest version.

This is what happens with useLegacyLogin: true
Logs: https://pastebin.com/80bHwcr5
The output on my minecraft screen says Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: Index 110 out of bounds for length 5

This is with useLegacyLogin: false
Logs: https://pastebin.com/k3Qretix
The minecraft output upon joining to start Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: Index 7167 out of bounds for length 5
Sometimes it is just Disconnected
