Boot error [30605] [504]

[BlackWingRegulus]

I am getting the error listed above.

I was able to connect yesterday, and none of my security settings or other system settings have been changed.

I've reset both my router and my computer system, and confirmed I'm able to navigate to both this site and others.

None of the security settings on the router hardware have been changed since I was able to successfully connect.

The game is offline for maintenance and patch 4.4.

Also, yesterday and before, when you logged into the game, you got a pop-up screen that had all of the info on the downtime, which is happening now until around 3:00AM PDT 9/18
