When the Administrator attempts to log on the Symantec Endpoint Protection Manager (SEPM), the following error is presented:
Error: Failed to connect to the server.
Com.Sygate.SCM.Server.Util.SCMServerError: Failed to connect to database after tried 20 times. Please start the data
Failed to connect to the server.
When the SEPM was installed, the default port (8443) was already in use, and the service "Symantec Endpoint Protection Manager Webserver" was missing.
Change the port to an unused port by following the Disaster Recovery procedure. In the event of a Disaster Recovery procedure to restore the SEPM Webserver service, choose a port number different from the default port 8443.
