So for the last 24 hours on top of the Error 209&301 and a full new install. I haven't gotten past Character Selection. Always being booted back to Login after I selected a character and logged in. Loading screen would start then stop spinning with a kick and the message, Error: An Error has occurred. Please wait a few minutes and log in again.
The cure shut off all addons. I also realized my load time was just as fast as when the game first came out. So I then went through the addons one by one to see which one kicked me, and the culprit was:
ESOHEAD
After shutting off ESOHEAD and ESOHEAD Markers my game loads extremely quick and with no issues. I'm guessing with every zone the game has to reload some saved variables from addons. A dynamic data collector that is not efficient to the games load will cause issues. Good to know for when I write addons.
TLDR if you have load screen time issues or trouble going from zone to zone, disable addons and test.
