Hello,
I’m sorry to hear that you are facing issues with the SEO Analyzer showing an API 400 error. This error can occur due to various reasons, including website status, API timeout, or API requests being blocked by a firewall.
To troubleshoot this issue, please check the following:
-
Check Website Status: Ensure your website returns a 200 status code. You can use a tool like httpstatus.io to check your website status.
-
API Timeout: If your website takes more than 30 seconds to load, it can result in an API error.
-
API Requests Blocked by Firewall: Your server security or firewall might be blocking API requests. Whitelisting the IP 46.30.211.100 and the user-agent RankMathApi/2.0.2; https://rankmath.com can resolve this. If you are using a different IP, please let us know.
If you have already checked these and are still facing issues, please reach out to our support team directly from here. They will assist you further in resolving this problem.
Thank you for bringing this to our attention, and we appreciate your patience while we work on resolving this issue for you.
Kind regards,
Rank Math Support Team
