Cause

This Warning is displayed when the Windows services that authenticate and verify the integrity of the license are unable to reach the Schneider Electric licensing servers.

This can happen when the server looses it's connection to the internet or when the system's host IDs experience any sort of change due to OS updates, IT policy implementations, etc.

This could also be the result of the license being activated with the ONLINE method during system commissioning when the internet is enabled on the server, virtual machine or NIC and then later disabled after commissioning is completed.

Resolution

To check if the license was activated online or offline, follow the steps below:

Launch License Configuration Tool
Click on the License Information button while holding down the "Ctrl" and "Shift" keys.
Check in the title bar of the dialog
If the string starts with "OFFLINE", then it was activated offline. If not present, then it was an online activation.

License Offline activation check example

The solution is to return and reactivate the license in offline mode.

If you are unable to return the licenses using License Configuration Tool in offline or online method, then we suggest contacting following the instructions in the article linked below:
