Symptoms

Error message appears at the start of the processing or during any action in the License Manager: Unknown error. Error code: 0xFFFFFFFE Diagnostic Message: Name or service not known

Cause

This error can occur when the ServerAddress parameter in the LicensingSettings.xml file is incorrect.

Resolution

Please make sure that all LicensingSettings.xml with this parameter have a correct value. Here is an example of incorrect configuration:

<MainNetworkLicenseServer ProtocolType="Sockets" ServerAddress="license"/>

To resolve this issue, please change the "license" to the IP address of the server that is hosting the license. If the license is hosted locally, please use the 127.0.0.1 instead.
