This has been happening to my main character since last night. I am able to login to the lobby without issue. My connection is labeled as "excellent". When I attempt to login with this character it goes through the loading process and then I am instantly disconnected with an error 90000. I have gotten the same error for over 12 hours.

I thought it must be me, but after restarting everything I could updating everything I could think of, I decided to make a second character on the same realm. Unbelievably, that character is able to login again and again.

Does anyone know a fix or solution that worked for them?
