Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Please ensure that you are using the latest version of the Rank Math plugin. You may refer to our changelog page here: https://rankmath.com/changelog/
Then go to WordPress Dashboard > Settings > General, and make sure that the “WordPress Address” and “Site Address” have the same setup.
Meaning both URLs have the same exact protocols. They should be matching and not have a mismatch.

Now you will need to reconnect your website by heading over to your WordPress Dashboard > Rank Math > Dashboard > Help, disconnect and reconnect your Rank Math account

If the issue still persists, please add the following filter on your website and then reconnect to your account one more time:
