Random disconnect then no rejoin option

comp game crashes when doing well. I heard rumors that lag switch glitches were back, I was just in a comp game and this is the second time this week that I am doing well and all of sudden the game crashes for no reason, my internet and such are stable, it crashes OW2 and then says reconnecting but fails ever to rejoin. and now because the game does not have a rejoin I get a penalty. it seems the error is as soon as someone DCs it is auto banning and penalizes the person which stops it from allowing you to rejoin. leading to fake leaver penalties. and it is egregious they do not even bother letting people contest leaver penalties, in what they want to be a competitive game.
