Can't enter fortress after exiting for the first time

[Kleinth]

First time unlocking the Sher'tul Fortress, after speaking with the npc there i exited to world map then immediately transmogrified some of the gems i had to get power for the crystal, luckily i had enough crystals to unlock the tp to fortress. I used the tp on the world map to enter but the door that previously unlocked was sealed and couldn't got in. "this door seems to be sealed"
Sorry for low quality cropped screenshots, had to crop them because they were too big.
