Thank you for the reply,

What kind of connection do have and what is your ISP? The Log in Restriction could be caused by logging in at a different location or signing on from a new network. Make sure when you are logged onto the game, you are not logged onto the SQUARE ENIX ID on a different location (such as being logged onto the Mog Station and being logged into the game on a different device).

Just as Drakkin said, getting a security token would help alleviate the Log in Restrictions.

Hope to see you online!
