I created a Windows VM in a VNet.
I have a Qualys solution in Azure Security Center, with auto-provision set to ON, so a qualys agent has been automatically installed onto the VM. Good.
Looking at the VM extensions, I see "Provisioning succeeded" for the Qaulys agent. Good again.

BUT looking at Azure Security Center recommendations, more precisely loking at the control "A vulnerability assessment solution should be enabled on your virtual machines", I see my VM in the list of "Not applicable resources" with the message "The extension might be corrupted, please try to remove it and deploy again".

Why is my agent not seen as working by Azure Security Center?
Notes:
- everything is good on Qualys server, the VM is listed in the list of handled assets, and vulnerabilites are also listed, so the agent is correclty transmitting information to Qualys server, but not to ASC?
- the VM is correclty connected to the Log Analytics workspace of the ASC
