I have run servers in the past, using Hamachi, for trading on this forum. They worked fine with no issues. However, when my friend came over and tried to connect to a server I had set up for multiplayer, he was unable to do so. I have tried manually running it through terraria's multiplayer host and play option and also through TerrariaServer.exe. Either way, we encounter the same problem: I am able to connect to the server fine (through the IP listed on my Hamachi ID), however when my friend tries to connect he gets stuck on "Connecting to [IP HERE]." What exactly would the problem be, and why does it only seem to be happening with him?
