After much back and forth between support for SE and my ISP, and I have been unable to figure anything out. Only my main gets this error - and happens without fail.

I have tried:
Power cycling my router
Checked all ports, they are open and confirmed by my ISP
Tried on 2 different computers
Tried on 2 different WiFi's
Resetting computer
Resetting Router
Reinstalling FFXIV

I have been logging in every once in a while to try my main character for a while, to see if it was just clogged ports but I continue to get error 90k while loading my character.

Been trying to decide whether or not to resub but I guess I will have to if I want to play my main... lol
