I am asking for urgent help. sorry for bad english, i use a translator. Already for 3 days in a row, the server for two stopped working for me. When we played and weren't doing anything special, the athernos servers crashed with an error, I don't remember which one. The next attempts to play to the fact that when the second player enters, the server crashes for everyone immediately and closes, sometimes it gives the following errors:
"internal exception java.lang.stackoverflowerror" or "io.netty.channel.AbstractChannelAnnotatedConnectException: Connection refused: no additional information available"
That was when a certain player came in. We cleaned the player file and everything seemed to stop, but the error began to appear for everyone and even on different accounts, or when we recreated a new server. In Discord, we were offered to play via DYN-ip, that didn't help either. I really hope for help, because this situation has been causing discomfort for 3 days already.
