90000 Error and Square Enix Account Authentication Error

I had these issues when the game first launched and then after some maintenance and patches the issue resolved. I play all day Saturday and some on Sunday with no issues and then Tuesday when I logged in I started to get the 90k error and 2002 errors once again while I was in dungeons or just in town.

My wife's computer is right next to me and we share the same network and she is not having any issues on her end. Nothing has changed on my PC or network and I have not installed any new software or hardware.
