I did a random normal dung just fine theni requeued for another and was very long waitvso i tried to get out of queue and it wouldnt let me. Imreloaded my ui 3 times. Turned off addons i didnt need yet still couldnt get out of q.
I travel to Cyrodill or Imperial City (there's no fighting at the base, it's entirely safe). You usually get a choice to go solo. Once in there either use the wayshrines to travel elsewhere (Cyro) or walk out the exit (IC).
