Dungeon Finder broke

Hey guys, so i'm new here and began a horde/mage in Ragnaros sev and until yesterday was using the DF fine.. After doing SM-grave, queued again but the DF got bugged.. On the "time in queue" from <1 minute it got to 1h like i was queueing for that long and every time i tried to re-queue it just continued to count (even when i started the game/launcher again), now it just doesnt pass the "<1 minute" for as much time i'm queued... already logged off, exit/launched game, deleted the game folder and downloaded again... Does someone know how to fix this?

Thank you
