Games Halo 5: Guardians
1

I’ve been having problems with Halo 5 matchmaking services a lot. I’m desperate at the moment to know whats going on. The game keeps kicking me out of the matches BANNING me for doing so. It has banned me (4) times already. I just want to enjoy the game. PLEASE HELP! GT: ProElite222

NOTE: The message “LEFT FIRETEAM” keeps poping out.

Try going wired, and setting your nat to open.

I am wired. My nat type is always strict unfortunately. Don’t know how to fix it.

EDIT: I stand corrected. It’s “open” at the moment.

Is there any type of Halo 5 (343i) support number, email, ect, that can help me?
