www.subdomain.domain.com doesn't work.

I am having some problems with DNS records.

I have a subdomain that I can access by typing:

If I want to access it by

http://www.subdomain.domain.com there is an error.

I have tried to solve this problem by adding this dns record:

Host: www.subdomain.domain.com
Target: domain.com

I still get an error. :frowning:

How do I fix this problem?

If you want a www.subdomain.domain.tld-type setup, then you should use Secondary Domains to set that up.
