Hello,
I’m sorry to hear that you are facing an API Error: HTTP 400 error with your SEO Analyzer in Rank Math. Since you have already checked your website status using httpstatus.io and it returned a 200 status code, we can rule out that issue.
If your other website hosted on the same server account is not experiencing this problem, it might be related to the API requests being blocked by the firewall. To resolve this, you need to whitelist the IP 46.30.211.100 and the user-agent RankMathApi/2.0.2; https://rankmath.com. You can do this in your firewall settings or contact your web hosting provider for assistance.
If after whitelisting the IP and user-agent the issue persists, please feel free to reply here, and a human agent from our support team will assist you further.
Thank you for reaching out.
