After reboot, Symantec EDR Manager displays the message "Symantec EDR Manager is now Unavailable".
Resolution
If you used VMWare snapshots while EDR virtual appliance was running, the EDR virtual appliance is corrupted. Prepare to re-deploy the OVA file. See Additional Information for documents related to this unsupported use case.
At the CLI, run status_check to identify the state of the services on the EDR appliance.
If the output of status_check does not include the words "command failed", attempt to restart all services by typing: reboot
Create a support case and include the output of status_check as a separate comment.
