Website is working in netlify subdomain but not with custom domain from external DNS provider

I am developing a website, that is currently hosted at Then I configured my DNS registry, to point a subdomain to it. I followed the docs and created a CNAME entry to

Hey @dplucenio, you’ll want to add your custom domain here as well:
