For the last several days I have been unable to connect in Spartan Ops Matchmaking. I can play war games just fine. I have tried resetting the modem, the router, connecting things differently to my xbox, changing the wires, etc. and nothing seems to be working. I am able to find players and then it goes to the loading the map screen then kicks me back to finding players (on the bottom of the screen it says that all the players left). Eventually (after about 10 times of this) it will kick me back to the Spartan Ops menu and on the bottom of the screen says that it could not connect to Xbox Live and I need to sign in, however I am online the entire time. I have played plenty of times with no issue except for the last several days. I am out of ideas on how to fix this issue, especially given I can play War Games just fine. Please help me out! Thanks so much!
