Cannot get a match going??

I did search this but everything coming up is months old. I've not been able to play this game, as a killer, for months. What is the issue? Am I missing something? The longest I've waited on survivors to join is around 20 minutes. I usually only wait 10 at most. I just can't seem to get a single game going.

I think my rank is down to 19 or 20 since I can never play. 

So what is it? Is it something I'm doing or do I actually have to wait 30 or 40 minutes or more to play?
