My connection is wired. I live close to Sacramento where the servers are located. All the required ports are open. I turn off anti-virus and firewall before running the game. Ran it as administrator. Tried VPN. I even tried plugging the pc ethernet cable directly into the wall, losing wifi for my other devices in the process.

I don't know what else to do. No other games and apps seem to be affected. Only FFXIV. I don't even have to be in an instance. I can just be looking at the market board or standing around in an inn. I get 90006. Can anyone help?
