Hi, I ran into the same issue about 2 months ago. I restarted the userid process on one of my UserID box and that addressed the issue, that pair was using content update older than 8507. After that I upgraded all the UserID redist firewall newer content (>8507), I don't have that same issue again. Can you check if the firewall content release version is newer than 8507? (12/21/2021; updated 1/13/2022) A certificate used by PAN-OS software to authenticate to the WildFire Private Cloud appliance (WF-500) and URL Filtering Private Cloud appliances (M-500 and M-600 in Private URL Filtering Cloud mode) and that impacts User-ID redistribution expired on December 31, 2021. We released Emergency Content release version 8507 on December 21, 2021, to update this certificate so that PAN-OS appliances can authenticate to these private cloud appliances. Immediate action is required for all of your PAN-OS appliances that use either the WF-500 WildFire Private Cloud appliance or the M-500 or M600 appliances in Private URL Filtering Cloud mode. UPDATE: User-ID redistribution is also impacted and requires that you complete additional steps before you are able to utilize the renewed certificate. If you have not already done so, you must update your appliances to Content release version 8507 or a later version to ensure that these appliances (including hardware firewalls, VM-Series virtual firewalls, and CN-Series container firewalls) will continue or again connect to WF-500 and URL Filtering private cloud appliances. Please refer to the customer advisory for detailed information about utilizing your renewed certificate.
