Searched for a game for 1.75 hours. Can not play more than the first 10seconds of any match of any type. Need help please.

I played the beta and had fun, had a few connection issues. Now, I can't even play more than 10 seconds of any match all without getting kicked. I've tried all three game types and nothing works. I find a game in two seconds, but can't stay in it after the match starts. I've restarted the game, Xbox, signed in and out, restarted my router. Everything. Nothing works. Can someone help me please. Thank you.
