Same, I have been trying to leave a dungeon for 15 minutes. Got one "Unknown Error" logout, logged back in and trying again to zone out to Stormhaven...(still no luck)
Wasn't even a day. Was about 12-16 hours. Hopefully now with this issue happening less then 24 hours later. They can address the issue once and for all.
Because this is the exact same thing that happened at 11pm Last night.
