Hello, everyone,


we have had this message in the system log for two or three days, is there currently a problem with the Palo Alto Cloud?


Does anyone else have this message too?


Thank you.

It's not a widespread issue, but since this is all distributed there could be an issue simply with your local cache.

We have been seeing this too for several days.  We cannot find a resolution to this.

Same here. I have an open TAC case on the issue

Please let us know the TAC case resolution on this issue.


My workaround about this issue is based on https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u0000001Uc6CAE 

First I checked if DNS security subscription on my firewall is valid.

After I reset the local cache with command "clear dns-proxy dns-signature cache", the error message stop appearing in system logs and the local cache it's regenerated.
