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

I apologize for the delay in our response. If you can only connect to the game using a VPN, then you are most likely running into an issue along your route to the server. The VPN will take an alternate route that does not have these same issues.

For further assistance, I'd suggest contacting your ISP and making a report with them.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
