Me and my partner are trying to create a modded world over lan. We have tried removing firewalls, changing ip settings, resetting the network and many other things but still no luck. LAN works completley fine on vanilla but not on forge. We have tried multiple versions and have even removed all mods from forge but LAN still does not work. The option to join does not show up and upon entering the provided port number it says: failed to connect to the server. Network is uneachable: no further information. How can it work on vanilla but not on forge even with no mods? Any suggestions would be appreciated.
