NTP fails with Windows Server

Hello guys,

I installed two BIP-IP last week (16.0.1), cannot synchronize with NTP servers (Windows Server).

[root@LB01:Peer Time Out of Sync:Changes Pending] config # ntpq -np

    remote          refid     st t when poll reach  delay  offset jitter

==============================================================================

 172.16.155.42  .INIT.         16 u  59  64   0   0.000   0.000  0.000

 172.16.155.45  .INIT.         16 u  58  64   0   0.000   0.000  0.000

Came across this article (https://support.f5.com/csp/article/K03294981), did the change on f5 a few hours ago, but still no luck...

Any chance someone had the same problem and was able to resolve it?

Thank you!
