I have added a CNAME from subdomain.example to subdomain.example1 . The result I have is “Apache is functioning normally” when I open subdomain.example.com. I am unsure why it does not show the second domain, as when I check the dig command in terminal it appears to point correctly. Is there some kind of config I need to perform in subdomain.example1.com for it to display?
Unless the server is configured to serve both hostnames, a CNAME record won’t just duplicate the site. You would need custom code to do that and it’s not built in to Cloudflare.
