Failed to check upgrade info due to generic communication error

L3 Networker

Hi all


since last night i get alot of erros from wildfire, antivirus updates, content updates...

All sheduled updates and even manual checks from the gui bring up errors.

No HA config.

Problem is on a 3020 and a old 500.

Ping and trace work to eu.wildfire.paloaltonetworks, wildfire.paloaltonetworks and updates.paloaltonetworks

DNS seems to be ok.

System Log shows 'Connection to Update server: completed successfully, but searching for updates takes a long time and brings up the error again.


Anyone else with these problems?

My mailbox is spammed with warnings from wildfire (sheduled to all 15 min.).





Accepted Solutions

WildFire is currently experiencing an issue providing updates through the CDN infrastructure and Palo Alto is currently monitoring a fix that was pushed at 0301 UTC that should address the issue. 

I'd recommend that everyone sign up for communications at if you haven't already so that you receive outage and maintenance notifications.

Have you checked the URL filtering log? Had a similar issue with a customer that enabled "continue" action on a bunch of categories and was intercepting their own update connections

Hey Karsten,


We're experiencing the same issue as well, started happening last night same as you.


Checked Wildfire on our 5250 and it's all up to date as of 11 minutes ago (4pm), but it's still continue to spam our email inboxes with the same message "Failed to check upgrade info due to generic communication error". We temporarily turned off URL filtering and it's made no difference whatsoever.


If the issue continues to persist tomorrow I'm thinking about raising up a support case with Palo.

We have been seeing this intermittently across all our firewalls for the past month or so.  Occasionally, we see a lot more of these errors than normal and this past weekend was particularly bad.  We changed the update URL to one we found in another post and it doesn't seem like it makes a difference so we changed it back. This is affecting our 220, 820 and 3220 models (running 9.0.6)


My guess is that whatever update source Palo is using is either busy or having problems. It is definitely a transient issue and other than email/alert nags, we also seem to get an update at the next attempt. But the last few months have certainly been worse!  



checked URL Filter. Was not enabled on the rule for PA Updates.

Turned it on now with action alert to get some URL logs.

Not better now.

Sometimes it works but still a lot errors.


The errors showed up in the last month. But only some.

Now i had them every 5 mins.

Since yesterday it´s a bit better and manual search also worked which did not before when i posted my request.


So it seems the problem is not on my or your site but on palo or their download storage (google cloudstorage?)

 Thanks so far for all your replies. Lets see if it gets better soon.



Ours is set to alert.  I can see it in the URL log and all looks good there. 

@loveground Scott, would be cool if you open a case and let us now if there is something new.



Yeah I'm going to open up a case, see what comes through from it. Temporarily disabled the email alerts since it's literally been hammering our inboxes every 5mins.

Funnily enough, after raising a case and then re-enabling the email alerts on our firewall to test if the problem still persists, we are not getting spammed anymore.


So case has been closed.

I left the email notifications on, partly because I wanted to see how big of a problem it was going to be, and also so I had some good data for a support call.  I received one notification at 7:09am (Central) from one firewall and have received none since yesterday at 8:00p.  I am not sure if something changed on Palo's side, but I agree that the alerts have pretty much stopped in the last 12 hours or so.
