My chrony time server with the version: 3.5-6ubuntu6.2, can get the time from another internal time server but not from time servers on the Internet. Could you please help me to synchronize my chrony server with a time server from the internet?
The working internal ntp time server can synchronize with the Internet
systemctl status ntp
● ntp.service - Network Time Service
Loaded: loaded (/lib/systemd/system/ntp.service; enabled; vendor preset: enabled)
Active: active (running)
But the chrony time server can't do it I restarted the network and checked that chrony is online:
netplan apply
chronyc online
200 OK
The chrony service is running
systemctl status chrony
● chrony.service - chrony, an NTP client/server
Loaded: loaded (/lib/systemd/system/chrony.service; enabled; vendor preset: enabled)
Active: active (running) since Mon 2020-12-28 09:59:58 CET; 11min ago
Docs: man:chronyd(8)
man:chronyc(1)
man:chrony.conf(5)
The connection to the internet is possible
telnet www.google.de 80
Trying 216.58.212.163...
Connected to www.google.de.
nc -zvu ptbtime1.ptb.de 123
Connection to ptbtime1.ptb.de 123 port [udp/ntp] succeeded!
This is the config of the chrony server
nano /etc/chrony/chrony.conf
pool pool.ntp.org iburst
server 192.53.103.108 iburst
pool 2.pool.ntp.org iburst
server 0.de.pool.ntp.org iburst

pool 0.ubuntu.pool.ntp.org iburst maxsources 1
pool 1.ubuntu.pool.ntp.org iburst maxsources 1
pool 2.ubuntu.pool.ntp.org iburst maxsources 2
