low priority queue resetting randomly

i am trying to play my last low priority game, however it seems impossible to actually play. while waiting in the queue, the timer randomly resets back to 20 mins, when it reaches zero and the timer reverses, instead counting how long i have been waiting in the queue, it gets to a random point and stops. the ONLY way to stop this happening is to leave the queue and restart it, resulting in waiting another 20 mins so far i have had to quit and restart the queue 5 times.... is this a known issue? and is there any workaround?
