The default HTTPS port for Apache is port 443. If Symantec Endpoint Protection Manager hosts other HTTPS websites, port 443 may already be assigned to one of these websites. You should use a different port for new installations to minimize conflict with any applications that already use the default port 443. If you want clients to use the default port to communicate with Symantec Endpoint Protection Manager, you should first verify that port is available.
If you customize the HTTPS port number after you deploy the client software, the clients lose communication with the management server. They reestablish communication after the next client update from the server, which contains the new connection information. You can also use a Communication Update Package.
After you complete this procedure, you enable HTTPS client-server communications.
