If you’re trying to access Amazon Prime Video but are being redirected, it may be that it has detected that you’re using a VPN. This means you’ll need to disable your VPN or connect to another server for a different IP address. Be sure to clear your browser’s cache and cookies for any changes to take effect.
Amazon geo-restrictions and VPN detection are some of the best technologies available, and so it’s really important to use a reliable VPN service to avoid this error message from recurring.
