Cause
There can be several reasons that cause this message to appear and they are usually related to how the firewall is able to reach out to the internet.
Resolution
- Verify the firewall has DNS servers configured to be able to resolve updates.paloaltonetworks.com:
From the WebGUI: Go to Device > Setup > Services:
- Ensure the firewall has an appropriate Default Gateway and interface speed and duplex are set to match the switch it is connected to:
- Make sure the firewall is able to resolve FQDNs:

- Traceroute out to updates.paloaltonetworks.com verify the correct path is taken (the final host will not reply)

- Verify Service Routes are set as expected, some services may need to be redirected over a dataplane interface in case the management network is isolated,
- Make sure the firewall is allowed to make outbound connections through the security policy:
- If ssl decryption is used, "Verify Update Server Identity" may need to be disabled if updates.paloaltonetworks.com is not excluded from decryption:
