Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Please make sure that you’ve connected the correct Google account and not connecting to Google Search Console via a domain property but rather a URL prefix and that you have verified the correct version of your website on the Google Search Console (HTTP or HTTPS, www or non-www).
After that, please follow this guide to remove Rank Math App from your Google account and reconnect it with all the required permissions, and see if that resolves the issue: https://rankmath.com/kb/analytics-issues/#expired-google-oauth-token
Let us know how it goes. Looking forward to helping you.
Thank you.
Hi Siam, thanks for your help. I checked everything and reconnected it with all the required permissions.
But After it there is still no result in the Google search console. My Website is not shown.
Can you help me?
Thanks a lot,
Christopher
Hello,
Before further troubleshooting, please ensure that you have verified your email/account as the owner of the property. Go to your Google Search Console > Settings > Users and permissions:

If the issue still persists, then 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:
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):

Looking forward to helping you.
Thank you.
