Since me and my friends started using Aternos, a number of problems occasionally occur when we access the server that seems to cause us to be stuck in a void where terrain and entities don't render and then get disconnected complete. So far we've encountered two specific error messages concerning this after we've been forcibly disconnected and have occasionally been able to solve them temporarily but sometimes aren't able to no matter what.
These are the specific error messages:
"Internal Exception: Java.IOException: An existing
connection was forcibly closed by remote host."
(This is the common error.)
"IO.Netty.Channel.AbstractChannel$AnnotatedConnectException"
(Only one of us has encountered this.)
