Everytime I try to join a server with this mod, I get this error:

Internal Exception: io.netty.handler.codec.Decoder Exception:java.io.IOException: Packet was larger than I excpected, found 1 bytes extra whilst reading packet 63

I have tried joining many different servers and this always happens. I am not very good with technology so I have no idea what to do, or if this is enough information for someone to help but if anyone knows how to fix it please let me know!
