ZENworks Configuration Management
In some cases, post reboot after applying the appliance security patches, a transient error is seen when trying to login to the Appliance Console 9443 port.
If refreshing the browser does not resolve this error then please contact your system administrator.
This error is most often caused when the datamodel-service fails to start or is not running on the Web-Server.
In some cases, the problem will correct itself after some time up to an hour.
Or try restarting the datamodel-service with: rcvabase-datamodel restart
The status can be checked with: rcvabase-datamodel status
Otherwise it is necessary to collect logs and contact ZENworks support Micro Focus Customer Care. For more information about appliance logs see https://support.microfocus.com/kb/doc.php?id=3418069
