Hi! I think the problem resides in the NTP servers you have.
Try doing the following:
At the ha cli type login
Then type vi /etc/systemd/timesyncd.conf
Press i
add the line NTP=time1.google.com time2.google.com time3.google.com
and change the FallbackNTP to FallbackNTP=0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org 3.pool.ntp.org
Press ESC and type :wq
Type reboot
