I am currently in Abu Dhabi and am trying to sign up for the home test. Every 2-month option I select returns the following error messages:

Please make the following corrections: No test centers found based on your search criteria. Change search criteria or enter a specific city location and try again.

Complete the information below to find available test centers and dates. If you have an advance reservation code, you may schedule your test appointment with the advance reservation code. Based on your geographic location, you may have the option to take the GRE General Test at home. To confirm availability of testing at home in your area, sign in or create an ETS account and begin your registration. Do not enter a location in the search below. This search will only show tests available at test centers.

Did i do something wrong for it to not allow me this option?
