I've been playing the modpack "Lay of the Land". At the start it was perfect, we didn't had any problems, but after some time the server started crashing moments after I opened the server.
It appears the message Connection Lost - " A Fatal error has occured, this connection is terminated. I've tried to start the server singleplayer mode and still doing the same thing.
I searched for solutions online but didn't found anything related to my problem, how can I solve this?
