Apache don't start on ssl port 443

After install CWP the http daemon don't listen on ssl port 443 but only on port 80.
tcp        0      0 :::80                       :::*                        LISTEN      10265/httpd
Same thing after httpd restart

Therefore the crt is well installed on my domain

Hello.

Yes, by default Apache is not listening the 443 port. You can install SSL certificate and it should be works.
