"Lost Connection to opponent" in a ranked match

Playing a Ranked match vs another European player in low ping (<80) everything seemed fine until the 3rd or so matchup came on the roulette, then I got “Lost connection to the opponent” and was back to the main menu screen and out of the MM queue too. Neither player got the “win” or the “loss” as it were and we were both still connected as far as we could tell. (vs JJTam if that is any help re: the log)

I am not sure if the log is anything useful here, but this does seem to happen periodically still for me. Maybe a server issue still?
