FIX- The fix is logging out of your Microsoft account and then logging back in again
-Thanks Rare.
For some reason, Halo MCC (PC) will not let my play and pops up with a Contacting Server Message every time I try and play the game. The error message says “contacting the server to get the latest matchmaking data. Please wait.” I have been waiting over the last couple of hours and I still don’t know what changed from when I played it 16 hours ago. I have tried repairing the game via steam, restarted my computer and it did not change anything. I can play other online games without any problems so it is only Halo MMC, also single-player activities that like solo custom games, campaign and firefight all work fine it is just when I need to connect to other players. I do not know what problems I am having so if anyone is able to help that would be great.
