Stuck on title screen / BLZ51914400

After the Cata prepatch launch, I have been stuck on the title screen with no way to get logged in. Upon launching the game I am prompted to input an authenticator code (which is weird, considering I am already logged into Bnet and should be authenticated through that?) and after typing in a code from my mobile app, I am presented with a disconnected popup with the following error code.
BLZ51914400
I have reinstalled, I have deleted cache and renamed WTF folder and repaired, I have deleted all my addons, reset router, reset Bnet, disabled my authenticator and nothing is working.

Lots of advice from the staff about this error code:

I have tried most of the solutions listed in that post and it seems to not be a network or firewall problem on my end. All other editions of WoW open just fine and log in without any problems.
Also, the error code from for the post you provided is slightly different from the one I have received consistently.

Any update on this? Am also having the same issue

same issue here as well. ALl other editions of wow work without issue.
