LTSS registration for PAYG based Azure instance failed

The following OS releases are running in Microsoft Azure Cloud: 

SUSE Linux Enterprise Server for SAP Applica­tions 12 SP5
SUSE Linux Enterprise Server 12 SP5

For a SLE 12 SP5 based Azure instance the Long Term Service Pack (LTSS) registration failed, even if it was successfully registered to the SUSE provided update infrastructure based on RMT.

Example output:

This issue is reported to Engineering which is actively working to get this fixed. Currently there is no workaround available.

When registering the LTSS extension in Azure the header does not contain the instance identifier.
