Can't play on my server without crashing. in Technic Launcher Posted May 24, 2019 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?
