Access points have their regulatory body set when they are ordered. As an example, a GR10 purchased in the US will have the regulatory domain of the Federal Communications Commission (FCC), dictating which channels can be used on the device.
If the public IP detected on the GR10 is mapped to another country, like Japan, this alert can be presented.
How to Troubleshoot
Be sure the public IP and the order region of the access point match. If the management traffic is using a VPN to another country, try avoiding this to see if the problem is resolved as a test.
