Just got the "BIGELOWE" error

Just wanted to play some before Gears 5 is out and struck with this error. I was in a ranked Guardian match, next round started and I was the leader and I soon as the countdown began, I was disconnected. Cannot connect to the online services whatsoever even after closing the game and restarting my console. Weirdest thing is that when I got disconnected I got a message from another player that just said “tee hee”. Any help?
