Can only open Solo

Hello

I’m having issues opening all but one game mode in Halo 5, the only one I can access is Solo mode of the Campaign. Started happening yesterday. Just two days ago I was able to play everything. My 14 day trial expired and I bought a 12 month sub to Xbox Gold. Should have no issues with any of the multiplayer modes.

I checked my network settings and tested both the network connection and the multiplayer connection. Both say they are good to go.

Any ideas on my next step?
