NTP sync to server 0.pool.ntp.org failed

[philipp_scherer]

Hello all,

we run an upgrade on our Panorama to 9.0.7.

Since a few days, I'm receiving this warning:

NTP sync to server SERVER failed, authentication type none

Same message for primary and secondary NTP server.

I switched from internal to external NTP server.  Same error.

I already checked:

CLI NTP status command

user@PAN> show ntp

NTP state:
    NTP not synched, using local clock
    NTP server: 0.pool.ntp.org
        status: rejected
        reachable: no
        authentication-type: none
    NTP server: 1.pool.ntp.org
        status: rejected
        reachable: no
        authentication-type: none

Firewall rules

Panorama is allowed to access external NTP servers. 

VMware tools options

Time synchronization with host is disabled.

Reboot

I did a reboot, same error.

Known Issues

Checked the know issues https://docs.paloaltonetworks.com/pan-os/9-0/pan-os-release-notes/pan-os-9-0-release-information/kno...I haven't found anything that matches.

Is somebody able to help?
