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

L1 Bithead

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?

Yeah i'm using Internal NTP server which it was on the previous software version 8.1.8 before the upgrade and it is IP not FQDN,

 

@PA-5220-Primary(active)> show ntp

NTP state:
NTP not synched, using local clock
NTP server: 10.1.130.12
status: rejected
reachable: yes
authentication-type: none

@Zakareya,

 

Have you configured any service route for NTP service?

Hi,

Yeah i tried with the default and with it vlan but at the end i'm using the MNGT Interface

Is this workaround working for all? We are also planning to upgrade to 9.0.7 and we have public NTP FQDN configured. I want to take all precautions before upgrade.

Hi,

My issue fixed by using the below command to restart the NTP service/process

debug software restart process ntp

Thanks Hamid Safarzadeh & Michel from Westcon and sure @SutareMayur 

@BK0007 

as i know version 9.0.7 is the latest stable version under 9.0 and i don't have any issue with BUT keep in mind that my NTP is an IP not FQDN
