If you are like me then you might be unlucky enough to get kicked out of ranked and unranked matches just before they end and get a penalty. I fixed this problem by uninstalling overwolf and everything that comes with it and now I can play ranked agian. This is just a suggestion and it worked for me so it might not work for you.
