All domain and sub domain, same page

[StephaneB]

NS should not have anything to do here, the domain and subdomain are only available with computer host file modified and pinging to the IP so not available trough real domain url or registrar records.

thx

change the ip address of the A record to shared IP that's it (where you host the DNS)

[Sandeep]

don't forget to add the sub-domain cname records to your current dns records

[StephaneB]

Nothing change :/

[Sandeep]

i recommend you to use cwp free dns service or cloudflare dns service

as i noticed no changes in dns

thank you to everyone for your help.

For those who have similar issue, quick reminder on the behavior faced: primary domain was working fine when subdomains where only redirecting to the main domain whatever the subdomain setup.

The solution was directly linked to the SSL certs:

The problem did not come from my NS I reminds that this is a dev server and not a production server.
It was linked to SSL certificates, the autosigned cert used for dev was not wildcard and so blocking for https access to the subdomaine, I created a certificate (auto signed) for each subdomain, and not just for the primary one, which have solved all issues.

thx & bisou from french guy
