    The interception now works. It started working all of a sudden after many days of having installed the .CER certificate on the test system; very strange.

    Now, it works as expected (verified on user PC's browser - common name shows Azure Firewall Manager CA). However, the firewall application logs does not show if TLS inspection took place on the user PC. Is there a specific query to be written in order for the firewall to show that? Else, it is impractical to verify the same.

    Thanks
