Thank you for posting in the Final Fantasy XIV Technical Support Forums,

I apologize for the delay in our response to your concern. If you are experiencing a log in restriction, please reset the password lift it. The connection error you are experiencing could be caused by congestion and many people attempting to sign in. If using WiFi, please try and connect directly to the router. Please also make sure the game is allowed through the fire wall as well.

Hope to see you online!
