PublicCloud Server certificate validation failed

Hi community,

I have an issue where system log shows severity high for an event:

tls-X509-validation-failed

and the description:

Palo Alto PublicCloud Server certificate validation failed

Dest Addr: sg.wildfire.paloaltonetworks.com

Reason: unable to get local issuer certificate

Palo Alto PublicCloud Server certificate validation failed

Dest Addr: sg.wildfire.paloaltonetworks.com

Reason: self signed certificate in certificate chain

I tried to use the following commands and it does resolve the issue:

> debug software restart process device-server
> debug software restart process management-server

However, I'm not so sure what is the root cause of this issue to happen and why these commands resolved the issue. Can someone highlight me on this?

Could be a problem in the backend.

I've seen these errors happen also when there was a WildFire incident:

Kind regards,
