Hello, title says pretty much whats up. I think it may be mod related, as after I placed a block belonging to a mod (McCrayFish Gun Mod) the server shut down and kicked me out. I've tried erasing player data as advised in some threads here, but problem still stands, every time I start the server, all fine and dandy, but as soon as I join the server shuts me out and closes. The latest log is in the attachment below.
Its Minecraft 1.18.1 and Forge version is 39.1.0
Thank you! 
Yes, I am suffering from the exact same issue, I can't connect to my server for 5+ days and have similar messages
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?
