Hello,
I’m sorry to hear that you are experiencing an HTTP 400 error. The HyperText Transfer Protocol (HTTP) 400 Bad Request response status indicates that the server cannot or will not process the request due to something that is perceived to be a client error. This error can occur for various reasons, such as malformed request syntax, invalid request message framing, or deceptive request routing.
In the context of Rank Math, you might encounter this error due to reasons like website maintenance, website status issues, API timeout, API requests being blocked by a firewall, or if your website is locally hosted.
To resolve this issue, you can check the status of your website using tools like httpstatus.io to ensure it returns a 200 status code. Additionally, if your API requests are being blocked by a firewall, you may need to whitelist the IP 193.138.6.5 and the user-agent RankMathApi/2.0.2; https://rankmath.com.
If you are still facing issues after checking these factors, please feel free to reach out to our support team directly from here, and we’d be happy to assist you further.
Thank you for bringing this concern to our attention. Let us know if you need any more help!
