Internal LFG Error

I am trying to queue for RDF but I am getting an error in the chat that says "Internal LFG Error". Earlier today I got into a RDF heroic dungeon where it said a DPS declined but I got sent into the dungeon anyway. In the dungeon I could only see three people in the UI but a tank was in the dungeon but not in the group. So we all left and now I can't seem to be able to queue for anything. I have tried to queue for RDF Heroic, Normal, Event and anything specific but nothing works.

EDIT: I was too hasty and now I found the solution by searching the forums.
