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