Internal Exception: io.netty.handler.codec.decoderException:java.IOException: packet was larger than i expected, found 32768 bytes extra whilst reading packet 53
I'm not quite sure but according to someone they tried entering the nether, and that's when the problems started(i have it turned off as far as i know, but apparently they were able to join?).
Now everyone who was online at that time cannot connect anymore, they login, and immediatly get disconnected and that error pops up.
Now a temp fix is when they join and i port them somewhere else.
I'm not quite sure if it has something to do with the nether but thats what i was told.
Can someone point me towards a fix please.
