Hello, all.

I have been playing COD MW2 on my Xbox One for a while. All of the sudden I open the game, go to multiplayer, hit Xbox Live and get a notice that says “You must be signed into Xbox live to play Xbox live matches.“ I hit okay and then log into my account. I then get the error 80151906. The message only says that you can not connect to Xbox live and asked if I want to test the connection. This is the only game that is giving me problems. I have play COD 3 online recently with no problem. I don’t know why only MW2 is giving me this problem. Any help would be appreciated.

I did check my NAT type and it says open. I’m on a wired connection.
