Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Please get in touch with your host and make sure the IP 46.30.211.100
and the user-agent RankMathApi/2.0.2;
https://rankmath.com
are whitelisted on your firewall.
Once done, please head over to your WordPress Dashboard > Rank Math > Status & Tools > Database Tools and click the Clear SEO Analysis
and Remove Transients
buttons to flush the SEO Analysis cache.
Please clear your website and any server-level caching on your site before doing the SEO analysis again.
For more details on this issue, please check this URL: https://rankmath.com/kb/api-http-400-error/
Let us know how it goes. Looking forward to helping you.
How can I change it?

Hello,
In this case, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP 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:

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):

Looking forward to helping you.
Thank you.
