"Could not find a server that was suitable..."

Hi, I’m not really sure what to do about this. I turned on my xbox after a few weeks hiatus and found that i’m unable to play halo 5 guardians AT ALL because all the playlists read the following message “Could not find a server that was suitable for all members of your fireteam”.

The only one in my fireteam is me. I’m not banned, the servers aren’t down, network is fine. What’s going on?

I am currently having the exact same issue. Did you find a fix?
