Trapped inside Abyssal Depth

I am kinda trapped in Abyssal Depth. When I try to portal out I get the Message:

Failed to join instance because: Disconnected from Server

Chat is still running and I tried relogging as well.... did not solve the problem... I picked up at the end also is still in my inventory after reloggin so no issue there.

Edit: just noticed there is a button now to login in town / hideout...

I logged into my hideout and the map portals are all gone. So I am guessing the Map itself crashed or something and the abyssal depth instance did not?
