I cannot play halo 3 Co-op with a friend online. The game does not get past the loading screen. I get tired to host and so did my friend. I have completed halo CE and Halo 2 without any issues co-op online i get a message saying “Connection lost. You have lost connection to the game.” I have tried to quit my game and try again but that does not seem to work at all. Anyone else have this problem
