I have upgraded to PAN-OS 9 yesterday, so far without 'bigger' issues, except:
See attached pics re Wildfire.
I would make sure that no traffic is being blokced with regards to this traffic. If nothing is, I would open a support case. There are quite a few defects in this release that are known and maybe this is a new unknown.
the setup has been working flawless under 8.x.x
I have disabled ssl inspection on the interface used by the pan to grab edls and the pan updates, same result. the ntp I have switched to an internal one, same result. error category is auth, error message says ntp sync to server fail, authentication type none. it's a plain vanilla ntp server.
one wildfire update has succeeded in the last hour, since then I am receiving the error messages above.
what a rollercoaster ride.
Would rolling back to the previous code work for your environment? I would even contact suppor and ask their assistance. Honestly they might have released 9 but I would wait until at least 9.0.3 or .4 until moving to it unless there is a feature you truly need.
