20.03 21:49:21 [Multicraft] Server shut down (starting)
20.03 21:49:21 [Multicraft] Restarting crashed server in 5 seconds
20.03 21:49:21 [Multicraft] Looks like a crash, check the server console. Return value: 1
20.03 21:49:21 [Multicraft] Server stopped
Pretty much, the problem is when I launch the forge.jar it crashes every time, however I can run the normal 1.10.2 server.jar. this severely confuses me as I cannot figure out why my Forge server will not launch.
