So I noticed yesterday or the day before yesterday that I can no longer host a server successfully. Before yesterday or the day before, I used to be able to host just fine with people being able to join and all (I had no ping, though). Now, people can't join my server, and it still has no ping. I've tried checking/unchecking the UPnP box in Network settings in BL, and it still doesn't fix the problem.
P.S. One of my friends says that when he tries to connect, it either reads "Sending challenge request..." over and over until "Request timed out." or nothing at all.
