Automatic updates broken?

Anyone else got trouble with Dynamic content updates??


  • Failed to download due to generic communication error. Please try again later.
  • Failed to download file

Did you try disabling this 'Verify Update Server Identity' under Device->Setup->Services.

I've see proxies that interfered with the update server certificate causing the NGFW to fail to connect.


Hope this helps,

Hi @RobinClayton 

Do you whitelist the specific domains that the firewalls require to communicate / to download updates ... ?

At least I am doing this and I had the same error since a few days. Today I found out that some firewalls (mainly PA-200 and PA-220) no longer communicate to the url as documented here: Content Delivery Network Infrastructure 

Since a few days these firewalls try to connect to As soon as I opened this URL the downloads were successfull again.

I added "SSL" application to the Palo Alto SW updates rule and everything started working again.

So something has been BROKEN again..


I did think updates were set to the external interface on the service router, but  I may have changed that after the updates were broken back in that autumn (northern hemi)...  With the SR for Palo Networks set on the external interface I am picking up  updates once more..
