Once done, you can run the SEO Analysis once again. If the issue persists, please share your URL with us so we can look into this from our end.

Hello,

Thanks for getting back to us.

You can whitelist the API and user agent in your Firewall or you can also get in touch with your web host and they would do this for you.

Hope this helps.

Thanks.
