Hello Minehut I've created a minecraft server on minehut a while ago, but all of a sudden one day it kicked me and my friend out at the same time. Then when we tried to join back in it said "io.netty.channel.abstractchannel$annotatedconnectexception". We have tried to join back a couple of times, and we went in, but then we werent able to move, and all blocks of a 20 block radius were gone! How can i fix this? Best regards Nivar
