I’m trying to create a CNAME record to point a subdomain of our custom domain to a branch deployment url like this:
test.customdomain.com → test–customdomain.netlify.app.
The custom domain is registered on Netlify and i’m using the Netlify DNS settings page to do this so i think it should work, but it doesn’t. When i go to test.customdomain.com it points me to a Not found page instead of the branch deployment.
The branch deployments are done by an Azure devops pipeline using the CLI command
npx netlify deploy --alias test ... if that matters.
How can i make this work? Is it even possible?
