this started 3 days ago. everything started while playing in 2b2t, without any reason I lost the connection of the server and then the next day I tried to enter the server but I always lost the connection and started to annoy me. On the third day I was unable to access the server, when I updated the list of servers and was unable to log in I did not receive a connection and another 5 servers had the same problem. when I tried to enter the server it gave me this: io.netty.channel.abstractchannel $ annotatedconnectexception. here more information
