POL-0011/1160 and FFXI-3001 errors while connecting.

[Taali]

Details:
I'm having issues logging on POL starting from the password screen, sometimes i'm lucky to get to the title screen and launch the game, but i keep receiving POL-0011/1160 errors while trying. When i do manage to get past these errors and log in my character i end up getting disconnected with error 3001 when zoning in specific zones like Aht Urhgan. I was able to log in my mule alt who's in Sandy though, but my main who's in Aht Urghan gets these errors and can't load in-game past "Downloading Data"

Steps:
I portforwarded my router, exhausted my options with the ISP, even getting my router replaced and route changed, disabled firewall, reinstalled the game, nothing seemed to work.
