My friend just came over to my house after a month of planning, and we were going to play on LAN with a couple mods, but it isn't working. We have the exact same forge and mods installed, but it's not working. I'm fine, but his problem is that when he tries to start a world, it says "Shutting down internal server". I was hoping someone could help us out with this, and maybe guide us... Thanks for feedback if you can
