Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Make sure that you submitted the correct XML sitemap to Google. You should submit the sitemap available on your website at https://domain.com/sitemap_index.xml
If you are sure you submitted the correct URL but you are still facing this error, check for a plugin conflict using the Health Check plugin.
If you are running W3 Total Cache along with Rank Math on your website, make sure you create another user agent group and add the ‘googlebot’ user agent to it.
We hope that helps. Looking forward to helping you. Thank you.
