After logging on to the Symantec Endpoint Protection Manager (SEPM), an error message stating "Failed to connect to server" displays.
"Failed to Connect to Server. Make sure that the server is running and your connection has not timed out. If you can reach the server but cannot log on, make sure you provided the correct parameters. If you are experiencing network issues, contact your system administrator. ErrorCode: 0x80020000."
This problem can happen when the SEPM Console is unable to connect to the SEPM Reporting Web site (https://<SEPM address>:8445/reporting). Some of the reasons this can happen are:
Confirm the Symantec Endpoint Protection Manager Webserver service is started
sc query semwebsrv
sc start semwebsrv
Check for port conflicts
If the Symantec Endpoint Protection Webserver service is stopped and fails to start, confirm that no other process is listening on the SEPM Reporter Web site port (default: 8445).
netstat -ab | find "8445"
To correct the port conflict, follow the steps below on the SEPM server:
Check for connectivity
Browse to the SEPM Reporting Web site (https://<sepm address>:8445/reporting by default). If the SEPM Web server service is running, and not blocked by a firewall, you will be prompted to log in to the Reporting Web site. This Web site uses the same credentials as the SEPM Console. If you are not able to connect to the SEPM Reporting Web site, check the firewall configuration on the SEPM computer and the Console computer (if using a remote console) for firewall rules that block the Reporting Web site port.
