Hello,
Thanks for contacting us and we regret the inconvenience caused.
Could you confirm if you’re getting an “API Error: HTTP 400” while performing the SEO Analysis?
If yes, then 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.
Once done, you can run the SEO Analysis once again.
Please refer to this tutorial guide for more details: https://rankmath.com/kb/api-http-400-error/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
