I am having a problem hosting:
One day (two days ago) me and Block Box were building in my server... worked fine, nothing wrong, except for the expected small amounts of lag.
Next day, Me and Block Box were going to play again, so I start the server, give him the same exact IP and password. It says he is receiving tile data, and remains at 1%. He tells me through steam that it really says, "receiving Tile Data: Complete!" and remains there. Then, I see, via my server hosting terraria window, that he has disconnected, or lost connection. It still says, "Complete!" on his for a few seconds, then I think it says, "Lost Connection!" for him, dunno for sure.
In other words, he played fine one day, and the next he kept losing connection.
Is it me, or him, that has done something wrong. I asked him if his firewall is blocking anything to do with it, he says no shortly after, and I check mine, mine isn't.
If anyone could help, I will be sincerely grateful.
