New game mode doesnt find anyone and freezes

When I first set up my the new mode and picked my 2 preferred roles (top and fill). It said estimated time 00:00 , I waited about 3 minutes and nothing happened. When i tried to click the X near arranging team it froze. The only way out of it is to log off and then log back on. I tried this about 5 times and im getting the same results. No game is found and it freezes. If i could post the picture i would.
