Excluding Cname for the sub domain

Hi There,

Please help me with the two issues.

  1. I have set the CName for the “primary domain” to “some whitelabel” which is working fine. But I have a sitemap file in the subdomain of primary domain sitemap.srihost.com/sitemap.xml how do I access this? Do I need to make any changes to CName settings? Currently, it’s not opening after changing it to Cloudflare name servers.
