Error 28

Hello,

I’m sorry to hear about the issue you’re facing with the API Error: cURL error 28. This error indicates that the operation timed out after 30001 milliseconds with 0 bytes received. It seems you are unable to use the SEO Analysis Tool for your website due to this error.

Based on the information provided, it appears that the timeout is causing the issue. Here are a few steps you can take to address this problem:

1. Check Website Status: Ensure that your website is returning a 200 status code. You can use a tool like httpstatus.io to check your website’s status.

2. API Timeout: If your website takes more than 30 seconds to load, it can result in a timeout error. You may need to optimize your website’s performance to reduce loading times.

3. API Requests Blocked by Firewall: If your server security or firewall is blocking API requests, 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 the firewall settings or contact your web hosting provider for assistance.

If after following these steps you are still facing issues, please feel free to reach out to our support team directly for further assistance. We are here to help you with any queries you may have.

Hello,

In this case, head over to Rank Math > Status & Tools > Database Tools > and click the Clear SEO Analysis and Remove Transients buttons to flush the SEO Analysis cache

Once done, clear your website and any server-level caching on your site before doing the Sitewide analysis again.
