Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
I’ve checked your sitemap, and it seems that you haven’t verified the www (or non-www) and HTTP (or HTTPS) versions of your website.
Please ensure that only 1 version of the sitemap is working (200 Ok status), and the rest are redirecting to it. You can also use this tool to check. Please follow the steps in this link:

You can get in touch with your web host to redirect all the traffic to its final version.
I hope that helps.
Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
