Hello Mocchizu, Thank you for posting on the Final Fantasy XIV Technical Support Forums.

The best place to address a i2501 error is by contacting support directly. It typically takes 24 hours for the escalated ticket to be resolved. If the issue still persists please contact them again and let them know it has been 24 hours and you are still getting the error.

Hope to be of assistance. Thank you for playing Final Fantasy XIV! Hope to see you online.
