Guild Wars 2

I am currently stuck on the quest Shell Shock.
The waypoint for the quest is in the Vigil keep behind a door, I click the door it says talk to the guard, I talk to the guard it says the area is under construction.
I cannot continue my story quest, How do I get past this door?

I don’t have that in my first character since I chose OoW but from your description, it sounds like a bug got you.
