I am having trouble configuring the DNS registries for the website blog.domain.it. The domain domain.it is hosted by Aruba (an italian DNS provider), I have bought a third level domain from them, blog.domain.it, which has a separate DNS console from the domain domain.it. I have tried many combinations of DNS settings for blog.domain.it, including, A records pointing to your balancer and CNAME records binding “www” and/or “blog” to “blog-production.netlify.app”.
I have also tried to set “blog CNAME blog-production.netlify.app.” in the DNS console of the domain domain.it as this page suggests doing https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/#configure-a-subdomain, with no positive results.
Woud it be possible for you to diagnose the current settings and tell me what’s wrong?
