Unable to sign in through steam, unable to complete version check.

Getting unable to complete version check error [30605][10009][19900][12030][19901][2]
and the code without the two at the end. I've tried uninstalling and reinstalling the game, forwarding the ports for the game, installing it on a different hard drive, deleting the FFXIV - A realm reborn folder under MyGames folder, and changing the configuration file with no effects. Is there any further way to resolve this issue? Game was fine two days ago.
