Plesk does not open – Could port 8443 be blocked?
You should make sure that your local network does not block Port 8443.
Blocking usually exists from corporate networks or from public organizations such as universities.
You should contact your network administrator if access to this port is restricted, to unblock it so that you can access it.
In case you continue to have a problem from another location where you know there is no blocking (home for example), then contact our technical department so that we can serve you immediately.
