After raise to PANW TAC checking and the issue is actually ISP BGP routing issue. PANW TAC perform a packet capture and notice there is no drop packet in firewall then PANW TAC confirm that the issue is from ISP. Due to ISP BGP route the traffic to some ip that is not firewall resolve to. After ISP fix the routing issue then the issue is resolve.

Hi @JiaXiang ,

 

It's not very clear how you've configured your policy.

For Windows Updates specifically, do you have a security policy in place for the application 'ms-update' ?

How is the traffic identified/blocked exactly ? Is the traffic blocked from a security profile perspective ?

Hi Kiwi,

 

In the security policy I have allow above FQDN any service and any application but the log result is showing aged-out. When using outlook in office the outlook will have  (!)  mark.

User who is using Global protect or I try to test using mobile network to perform Windows update is fine. I think the problem is not in Windows firewall.
