The apache that runs well at port 80 has nothing to do with the apache of the Zentyal administration. You can check if it's listening with "netstat -tlnp | grep 443". Also try to restar it with "/etc/init.d/zentyal apache restart" and look for errors with "tail -f /var/log/zentyal/*" while you execute the restart.
Sent all of the following commands ..
