Disconnected at end of "The Dark Inside" now getting 90002 error

Datacenter: Primal
Server: Behemoth
Character: Zen Hunter

As the title said, I had just completed "The Dark Inside", I was dead, and when the end cinematic began I got "Connection to the server was lost". Upon trying to log back in with my character I got a message that my character was still logged in, and since then I get a loading screen and then after a bit I get a 90002 error (it's been about 40 minutes of repeated attempts). It should be noted the Character Selection screen says my Location is still "The Dark Inside". I also want to note that I can log in on a new character I created as a test.

The same thing in all particulars happened to me. The situation was back to normal in a couple of hours.
