[solved] How do I create a subdomain and redirect it to a different website?

Is possible that has been solved this question many times but have found nothing that works for me (I searched on this forum, manual and documentation).

I follow this steps to create a subdomain to redirect it to a different website or create a website with a subdomain (Whatever you want to call):

-Step 1-
I created a new website following "Method 2" of Subdomains section fo documentation.
docs.ispconfig.org/creating-web-sites/subdomains/
I entered "subdomain.domain.com" in the domain field.

-Sted 2-
I created a FTP for "subdomain.domain.com" website.

-Sted 3-
I created a new CNAME record in records list on the "domain.com" zone following this tutorial.
docs.ispconfig.org/dns-basics/canonical-dns-records/
I created a CNAME record and I entered "subdomain" in Hostname field and I entered "domain.com." in Target Hostname field.


Then when I open "subdomain.domain.com" on Firefox I only achieve a Server not found page.

Where is my mistake?

Thanks

 

I wait for a months.
I try to follow the same steps and wait 24h again.

 

It is very strange.
The test that I have done brokes "domain.com". To make this test I added a "A" record to DNS with the "subdomain.domain.com".
I removed this record and I made a "CNAME" record with "subdomain.domain.com" and majority of subdomains (with or without own website) have sartarted to works fine.
I will create the subdomains that doesn't works fine to fix them.

 

Solved. Sometimes works and sometimos doesn't work.
