My brother and I each have our own Xboxs, and we have always been able to play Halo Reach together just fine. (Over the two Xboxs, with a party chat.) Just recently this thing started happening where we can play one game together, and then as soon as the game ends it sends me back to a Recruit and says "Halo Reach servers are unavailable, please try again later." My brother can continue playing fine. After about 10 minutes I am returned to my actual rank and can continue playing. We both have an open NAT type, and it says we both have excellent connection speeds. Anyone know what we can do to fix this? Thanks.
