Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

We apologize for the delay in our response.

If you are able to connect to the EU and JP Data centers, but not the NA one, you may be running into a routing or congestion issue on your way to that particular server. Since this would stem from outside of your home network, it would make sense that the troubleshooting you tried didn't solve the issue. If you are still experiencing this issue, you may want to try contacting your ISP and making a report with them.

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
