Can't confirm match

Happened twice in a row, says "Confirming match" and nothing pops up. I'm now banned for 15min. What can I do to avoid it happening 3rd time?

Edit: Okay it's now a 30min ban because I queued again after being able to watch some games that are currently being played. WTF ???

Edit#2: WEU is fucked. EEU worked. Thanks for the suggestion.
