Unable to download updates PAN OS 4.1.9 because of self signed certificate on updates.paloaltonetworks.com ?

[seniornwb]

Since november we have not received any content updates from updates.paloaltonetworks.com. We changed the rules so every update server (including amazonws.com) was allowed.

Now the updates start, I see a succesful connection to updates.paloaltonetworks.com, but the job remains in download state at 0%.

When I check the ms.log it shows:

Does the warning about a self signed certficate prevent the updates from beig downloaded ?

The brightcloud URL update works fine.

The certificate verification messages should not cause an issue with connecting to the update server.  We recently moved to using CDN for the actual content downloads.  You should modify your policies controlling outbound traffic to downloads.paloaltonetworks.com in addition to updates.paloaltonetworks.com.

We are working on updating the paloalto-updates application signature to include all update related services.  No ETA at this point but it is actively being worked on.  Once that signature is current you can just allow that application to any destination in your security policies.

If you continue to have issues downloading I would suggest opening a support ticket so we can investigate further.

Thanks,

Adding the downloads.paloaltonetworks.com worked fine.

Thanks for your help.
