Change ntp servers in Chrony

Hi, friends, we would set local ntp servers in our freepbx servers. We have made changes in /etc/chrony.conf but the sources follow the same:

^+ a.ntp.netplanety.com.br 2 6 27 1 -11ms[ -11ms] +/- 106ms
^- lrtest2.ntp.ifsc.usp.br 2 6 35 1 -13ms[ -13ms] +/- 71ms
^* sa-south-1.clearnet.pw 2 6 17 3 +16ms[ +29ms] +/- 83ms

Is there any way to change them? Thanks.

This is what I ended up doing:

Add to /etc/ntp.conf:
server pool.ntp.org

Then:
systemctl disable chronyd
systemctl start ntpd
systemctl enable ntpd
reboot

Hi, thanks by your reply, then with chrony it is not possible to change the servers?

It should be possible, but it isn’t really a FreePBX question.

If you don’t reboot, you may have to do something to cause the configuration to be re-read.

At the time that I was actively configured NTP I was only using ntpd, so I don’t know the exact process for updating chrony on the fly.
