Constantly getting dc-ed from games, then rejoin doesn't work

I’m getting dc-ed from comp games, then the rejoin button doesn’t work unless I restart…

Help!

EDIT: just dc-ed again, rejoin button doesnt work again, banned for an hour for nothing

I just had this on console, middle of a comp game where we were winning and i dc.
Restarted the game 4-5 times with the “Sorry can’t log you in” message. Finally got back in, rejoined the game and won and then lost 50 sr.
