Troubleshooting: License Error Because HA Servers Are out of Sync

Solution Based on Experience from the Field

This article provides a solution that has not been approved by the IGEL Research and Development department. Therefore, official support cannot be provided by IGEL. Where applicable, test the solution before deploying it to a productive environment.

Symptom

HA servers are out of sync preventing devices from registering in the UMS and throwing a license error.

Environment

  • High Availability (HA) environment

  • Firmware version: any

  • UMS version: 6.01 or higher

Problem 

Devices are not able to register in the UMS. Licenses are applied correctly. 2 servers appear in sync and another one is out of sync.

Solution

Issue is related to the UMS ID. If a restart of the out-of-sync server does not help, a workaround / solution is to back up the UMS ID from the UMS Administrator and restore it to the out-of-sync server. See Manual Synchronization of the UMS ID.
