Kicked from server after Competitive match completes

This is unbelievable, competitive match completed and after submitting match results "Kicked from server", of course my stats go with -. WHAT IS GOING ON ?

Second match after finish, still kicked from server, my stats go minus again, this is so buggy

This also happened to me once. For me, restarting the game fixed it.
ANYWAYS, you earn your points even when this happen. I can tell you because, after having that issue, I restarted the game and I was one rank higher.

I just lost connection during a match, couldn't reconnect, my internet connection was fine doe, there should be a way to reconnect to a running match ☹
