Hello, I have a server on Aternos that my friend and I have been playing on for a while, and all of a sudden the other day my friend couldn't connect to the server. As soon as he tried to connect his game would crash back to the launcher and say Java.lang.illegal.state.exception. I can still play on the server. We are playing on the latest snapshot 20w14a on java edition. We are using the right ip adress and have tried using the Dynip aswell. Any help would be much appreciated thank you.
A copy of the crash report is in the attachment.
