queueing while spectating a match doesn't work many times

After losing a match, i press 1 to queue and sometimes  minutes and minutes go by with nothing happening, i mean even the number of players in the queue isn't indicated but the game tells me i am in the queue. This continues even after the match has ended for all players. The only way to fix it is to escape back to the lobby and requeue and then it will find a match in less than a minute.
