Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
I tried to check for the default sitemap URL of your site but was unable to locate your sitemap and the default domain.com/sitemap_index.xml returning 404 page of your site. Can you please share the sitemap URL with us? So that, we can investigate the issue further for you.
Meanwhile, you may try checking the URL below to see if the steps may help you to resolve the issue:
