SolvedPlacement games question

I've been playing the placement games fine and finally I get to 8 wins yesterday. I go to play today and I can't find a match at all, it takes about 10-15 mins to even get in a match and I play with DMGs and LEMs. Could it be that my rank is too high so it's harder to find matches? I know it's not my internet because I can connect to community servers/casual matches fast and have good ping. Would like to know what's going on. Thanks.
