Please try to check whether all the Symantec Services are started in services.msc
If the manager service is not started, please check whether C:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\tomcat\etc\conf.properties is empty.
If the file is empty please add the below entries. You will need to know your server ID, which can be found in the most recent recovery file (C:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\Server Private Key Backup\recovery_timestamp.zip\settings.properties) and the specific version of the Symantec Endpoint Protection Manager in-use. You can find this in the "Version" column for the entry for Symantec Endpoint Protection Manager in Programs and Features in the Windows Control Panel.
Please run the Management Server Configuration Wizard, then attempt a login to the manager.
