Not permitted to play multiplayer games

getting that error when I try to join an online game. Why?
Im new to Halo, but can’t imagine I didn’t anything to get banned.
I am currently on a 14 day trial Xbox gold. I received 2 trials - one with Xbox, the other with halo game.
I played online with the last trial a week or 2 ago. Now using this other one before paying the account fees. Idk. That might be it?

Last time I checked, servers were down. I haven’t checked in a couple hours though.
