Example: I have my application Hosted on a Fixed iP VPS Example: 18.104.22.168
and clients want to run them in their own subdomain app.elcliente.io
Each client was instructed to create a DNS pointer A with the name of the created subdomain that they want pointing to the IP of the server.
ok since the DNS propagated and when pinging.client.io is pointing to the correct ip of the server. but the error page of the CPANEL goes out where it indicates that domain is not hosted.
Did you skip a step?
