Lately I haven't been able to acess my server. Its a 1.16.5 Forge server and for weeks I played in there no problem. But suddenly I couldnt connect to it. I got all sorts of messages from Disconnected to those longer java error messages.
I have tried several things, mostly what I see in the forums and trying to look for something that might not be right, but nontheless I got the same messages and never got to be able to connect again, and I saw noone having recently the same experience as I did.
What can I do?
