Matchmaking issues

After the countdown for matchmaking is gone and it’s “searching” I get booted back to the main screen. Has never happened until this last patch, I know of others it’s happened to also, except previously after about 20 mins it seems to go away, this time it’s been coming up to 5 hours and still no go. I’ve restarted my Xbox, my internet and rebooted the game itself. Still nothing… what can i do?
