internal exception io.netty.handler.codec.decoderexception


Recommended Posts

I made a forge server with the launcher and upon joining i get a error message.

(Medieval mod 1.19.2 client and server)

internal exception io.netty.handler.codec.decoderexception java.lang.indexoutofboundsexception:readerIndex(26955) +lenght(4) exceeds writerIndex(736955:PooledUnsafeDirectByteBuf(ridx: 26955, widx: 26955, cap: 26955)

Does anyone know how to fix this problem?

Thank you in advance

im getting erros just like this (the numbers are different) Im playing a slightly altered better minecraft modpack, i can play SP just fine with no issues. i copied the modpack to my laptop for my son. if either of us opens a world to lan the other cannot join, with this error popping up. doesnt matter who 'hosts', neither of us can join the other. i can find NO solutions at all. we are both frustrated. how can i get a log to post?
