Failed O365 Updates

L1 Bithead

We have two sites running PA-3020, one site is able to download O365 updates but the second site fails to download and install the updates. Not sure what im supposed to be setting on the 2nd Palo Alto to get this working.


They are both running 9.0.12 update

Hi @ImranRazaq 

Some more informations would be helpful. Like ...

  • Is the security policy the same on both firewalls?
  • Do you have url filtering enabled?
  • Do you have decryption enabled?
  • Did you check the logs if you see something blocked?
  • Did you check locally on a client so see which connection exactly isn't working (to which url)?

I cant seem to locate the security policy which allows traffic to pass through.

URL filtering is enabled on both
Decryption is enabled on the working on and not on the non working one

Since your configuration isn't the same between working and non-working units I would toss the fact that one of your sites is working out of the window. Troubleshoot the same way you would for anything else that is broken and ignore the working site all-together since they aren't actually the same (or at least, your comment makes them seem to not be the same).


Take a single "test" client that you can use at the non-working site and enable full logging for that client and take a packet capture of all of the traffic. When the update fails, review the firewall and the packet capture to identify what actually isn't being allowed to pass through the firewall. Chances are you'll see the traffic getting denied in your firewall logs and you won't have to go through the packet capture.
