Hi, @raduanastase. The CNAME is working. The lookup returns the record you created:
$ dig shop.funbible.net +noall +answer
; <<>> DiG 9.10.6 <<>> shop.funbible.net +noall +answer
;; global options: +cmd
shop.funbible.net. 3599 IN CNAME funbible-store.raduanastase.com.
funbible-store.raduanastase.com. 14399 IN A 220.127.116.11
The issue is that the server at that IP address
18.104.22.168 doesn’t know to see the site
funbible-store.raduanastase.com when referenced by the domain name
The solution will be a setting change with that system or hosting service to add that custom domain to the site in question. You will likely need to consult the documentation or support team for that other service to find out how to make the change there.
To summarize, the DNS record works. The web server that the DNS record points to is missing some configuration which will allow the correct site to be shown for that domain name.
If there are other questions about this, please let us know.
