Have done this twice and worked both times I kept getting Error 1017 and could get in queue to get logged into the game.

Just Create a new toon on another world, currently only EU servers available, than attempt to log in with that new toon. It might put you in queue or just log you into that server either way just quit and go back to your original server and log in the character you couldn't before and it should put you in queue and you will be in the server shortly.

This has worked for me twice this week when nothing else would get me logged in due to 1017 error or whatever.
