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.


Hi Cmuchong,


Have you tried what @JureKosmrlj said? Allowing the paloalto-dns-security app.

This has helped me.





IF you have checked this url link https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u0000001Uc6CAE


Then still same issue then please open up TAC case.

Thanks all, the solution finally was to upgrade to  9.1.11,10.0.7,10.1.1 (PAN-163800). If upgrade is not possible then a workaround is to use an in-country DNS (within China).

Looking for resolution for this one and I see no updates for almost 3 months.  


My device are not in China and have the same issue.


Any help out there?
