1 declared sitemap does not return XML
The URL responds, but the body does not open as an XML urlset or sitemapindex.
Consequence. A sitemap that is not valid XML is discarded. A common cause is the URL resolving to an HTML error page or a redirect to the home page.
If that is not intended. Confirm the URL serves XML beginning with <urlset> or <sitemapindex>, and that it is served as application/xml or text/xml.
