Www domain does not redirect

i have my website and page setup and the abc com redirects nicely to the dev page
but the www abc com subdomain does not connect timeout error

How are you doing the redirect?

Have you set a redirect rule or page rule? If you have, make sure you have a DNS entry for www. Set it to A 192.0.2.1 or AAAA 100:: and to be proxied.
