Terrarian
So me and my Girlfriend tried playing on a Hamachi server (set up and joined by me then tried on her computer), made a world and had it running through NTerraria Server, but we can't connect to each other no matter what IP we use. Just a note we are on the same router(In a dorm) with a ethernet cable hooked to each others computer that allows us to play regular Terraria. Any ideas?
Have you tried playing without Hamachi? If I understand Hamachi correctly, its purpose is basically to emulate a LAN connection over online connections; in other word, there's no reason to be using it over a LAN connection. I could have misunderstood what Hamachi does, though. I don't know if it'll make any difference playing without hamachi, but the only other thing I can think of is to make sure that you're using the IPv4 address, and that you use port 7777, but you probably already know that since you said you've played vanilla Terraria over LAN. Hope you get your problem fixed!
