Active/passive failover validation was performed using Azure HA configuration getting failed due to Azure token failed with exception <urlopen

L1 Bithead

I have a palo alto VM- 300 firewall(active/passive) with version 10.1.11-h4.which is hosted in France central azure region 2 availability zone and the azure environment.

While doing Azure HA failover validation on active/passive firewalls and validation passed.

When we upgrade the panos version 10.2.8 for both active passive firewalls. But hear we are getting validation getting failed.

We have raised the case with tac and engineering team. We have already had multiple sessions with Engineering and palo alto , whereby they have tested several code modifications but still they are not able to fix the issue. Please find below screenshot for reference. 

PAN-OS :- 10.1.11-h4 :- Azure authentication test is passed

PAN-OS :- 10.2.8 :- Azure authentication test is Failed.

Hello Roberto,

 

After adding the ms-office365-base app to the security policy rules and the session end reason became "threat".
We then identified that the URL security profile was blocking login.microsoftonline.com, so we added the URL to the custom URL category used.
The issue is now resolved and the root cause was that the app identification related to the traffic to the Azure API server (login.microsoftonline.com) changed from ssl to ms-office365-base when upgrading from PAN-OS 10.1 to 10.2.
