Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
Please make sure to whitelist the IP 134.90.148.114 and the user-agent RankMathChecker/2.0.0; https://rankmath.com.
If the issue still persists, could you please Flush SEO Analysis Data in Rank Math > Status & Tools > Database Tools and click the Clear SEO Analysis button then Start the Site-wide Analysis again?

If you’re unable to see that option, please note that some options are only available when you enable the Advanced Mode in Rank Math. If it’s not showing, you must have chosen to use the Easy Mode:

I hope that helps. Thank you, and looking forward to your update.
I whitelist the IP 134.90.148.114 and the user-agent RankMathChecker/2.0.0; https://rankmath.com and clear analysis SEO data. Then analysis SEO again. But the issue still persists. Please, help me to solve the issue.
Hello,
We tested your website using our Online SEO Analyzer tool and it appears to be working fine on our end. It seems that the conflict might be from StackPath.
Please test for a plugin/theme conflict. We have a great tutorial to help you along the way: https://rankmath.com/kb/check-plugin-conflicts/
In the meantime, you can use our online SEO Analyzer tool to test your website: https://rankmath.com/tools/seo-analyzer/
Having said that, the Online SEO Analyzer tool will not show the Focus Keyword section as the SEO Analyzer tools examine the website’s source. Further, Focus Keywords is something that doesn’t get added to the website’s source.
If the issue persists, then please edit the first post on this ticket and include your Server’s IP and WordPress logins in the designated Sensitive Data section.

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):

We really look forward to helping you.
The issue is solved. Thanks, Rank Math Support team. I really appreciate your assistance.
