API Error: HTTP 400 error

Hello,

Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.

Can you please share the URL of your website in the sensitive data section so we can check and assist you further?

Looking forward to helping you.

Hello,

Thanks for getting back.

I tried testing your site in our external SEO analyzer, it returned an invalid server response so it appears your web server is blocking access to our API.

Please make sure to whitelist the IP 134.90.148.114 and the user-agent RankMathChecker/2.0.0; https://rankmath.com.

If you are not sure, please ask your web hosting provider to do it for you.

Let us know how it goes. We are looking forward to helping you.

Hello,

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress logins 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:

https://wordpress.org/plugins/temporary-login-without-password/

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):

https://wordpress.org/plugins/wp-security-audit-log/

We really look forward to helping you.

Hello,

Sorry, but we don’t provide support over screen sharing. If you don’t want to share the login details then you use the following troubleshooting guide to check if some plugin is causing the issue: https://rankmath.com/kb/check-plugin-conflicts/

If the issue persists even when only Rank Math and a default theme is active then there should be a server-side blocking. Please contact your hosting provider in that case and ask them to whitelist the IP address that I have provided in my previous reply.

Let us know how it goes. Looking forward to helping you.

Hello,

I tried to check for a possible plugin conflict but the troubleshooting mode of Health Check isn’t working on your site and throwing an error.

In this case, we will need your permission to deactivate all the plugins on your site. Or you can create a staging site for us and share the login details of that. You can use https://wordpress.org/plugins/wp-staging/ to create a staging site.

And also please check if you have ModSecurity enabled in your cPanel. If yes, then disable it and check the SEO Analysis again.

We really look forward to helping you.

Hello,

Then please create a staging site and share the login details in the sensitive data section.

Thank You.
