I think I misunderstood. You can get into the game lobby but you cannot connect to other players? I had thought you could not go online at all. The connection between players is not controlled by us. All our server does is tell the players in the game the IP address of the other players. I think it may be a coincidence that other people are having problems. Maybe your provider changed something.
I will continue to look at this.
