Cant join multiplayer games

I have not been able to play any multiplayer games since 9/24. Every night I login, I am getting “Could not find a server that was suitable for all members of your fireteam.” I am playing solo. I have tried to do my due diligence, and searched for this issue for solutions. I have tried hard reset, clear MAC address, reset router, different internet sources. Nothing is working. What else could I try? I have been playing for years, and never run into this.

Thanks.

I have the same problem this last month

I was having the same problem last night, but XBL was having issues. Trying again right now…
