I've always used Hamachi for playing games with no problems before, but recently, when trying to log into my friend's game, I noticed that I would get timed out from the server randomly. It could be right after joining or only after a few hours. And I've noticed that whenever that happens, our connection in Hamachi switches from "direct tunnel" to "relayed tunnel", and I can only re-join the server once it switches back. No one else is having this problem but me, and I really don't know how to fix this. Any ideas?
