I am creating my own modpack and i suspect there is a conflict between some mods that is causing the error "Fatal error occured connection terminated" There is no way that i know of how to troubleshoot this. Every player that connects the server gets on for a few seconds after being disconnected. We all have the identical mod folder to that of the server. Singleplayer works fine for all of us and the mods work together there. The error that i get in server console is very incomprehensible.
