Group Disbanded

I had some issues with my connection and i was afk one game so i was put in a low prio,now when i wait for 20min counter to expire i get "group has been disbanded" even before the 20 min period is over,so when it is over im just back at selecting the lanes i want to play :P in 2 days i have not managed to enter the game not even once.

Im playing solo so there is no group :P
