dns-signature cloud service connection refused.

I am seeing in the System Log the following message "dns-signature cloud service connection refused"  Checking the traffic logs the management IP address is not being blocked.  Where do I look to resolve this error message?   Thank you.


I have the identical issue, have you been able to resolve it?

I worked with TAC and we were not able to resolve the issue.  The firewall is located in China so we believe the issue had to do with "The Firewall of China".  The issue since has resolved itself.

I'll open a TAC case also since the Timeout enhancement has not helped.

It seems you have to enable paloalto-dns-security app.

Does anyone have a solution for this? All our firewalls in China are unable to reach "dns.service.paloaltonetworks.com". The result are random DNS requests getting sinkholed and delayed.
