API Error: HTTP 400 error.

Hello,

I apologize for the issue you are facing with the API Error: HTTP 400. This error typically indicates that the server cannot process your API request due to a client error. Here are some common reasons and potential fixes:

1. Website Under Maintenance: Ensure your website is not in maintenance mode. If it is, switch it back to normal mode.
   

2. Check Website Status: Verify that your website is returning a 200 status code. You can check the status of your website here.
   

3. API Timeout: If your website takes more than 30 seconds to load, this could cause a timeout error.

4. API Requests Blocked by Firewall: Your server’s firewall may be blocking our API requests. You may need to whitelist the following IP addresses:

   46.30.212.200
   46.30.212.201
   46.30.212.202
   46.30.212.203

   You can do this in your firewall settings or ask your web hosting provider for assistance.

5. Locally Hosted Website: The SEO Analyzer module will only work on a live site that returns a 200 OK status when crawled from an external site. If your site is hosted locally, the SEO Analyzer will not function properly.
   

If you have tried these solutions and are still experiencing issues, please reply to this ticket with your website URL so we can assist you further. A human agent from our support team will take over and provide more specific help based on your situation.

Thank you for raising this concern!

Hello,

Thank you for your query, and we are so sorry about the trouble this must have caused.

Please head over to your WordPress Dashboard > Rank Math > Status & Tools > Database Tools and click on the Clear SEO Analyzer button to flush SEO Analyzer data.

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

If the issue persists then there is something on your server that is blocking the API.

In this case, please get in touch with your host and ask them to whitelist the IP 46.30.211.100 and the user-agent RankMathApi/2.0.7; https://rankmath.com.

We hope that helps, and please don’t hesitate to get in touch if you have any other questions.

Thank you.

Hello,

The issue with ModSecurity occurred because the user agent was added directly to the Apache configuration. Please remove the line containing RankMathApi/2.0.7; from your modsecurity.conf file to fix the syntax error.

After that, simply whitelist the IP 46.30.211.100 in your Plesk firewall settings and there’s no need to modify ModSecurity for the user agent.

If you’re unsure how to do this safely, we recommend contacting your hosting provider for assistance with adjusting the ModSecurity and firewall settings.

Once that’s done, clear your website and server cache, and try running the SEO Analyzer again.

Hello,

We apologize for the inconvenience. We just checked your website in our external SEO Analyzer tool and it seems to work. If your website is working there, it should too in our plugin’s in-built SEO Analyzer tool.

Please head over to your WordPress Dashboard → Rank Math → Status & Tools → Database Tools and click on the button “Clear SEO Analyzer”.

After that, re-run the SEO Analyzer again.

If the issue persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress login in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
