DDCLIENT setup help needed

Hello,

i installed ddclient on my dietpi

here is my config

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
protocol=dyndns2
#usev6=ifv6, if=eth1
#if-skip=Scope:Link
use=cmd, cmd=the command
ssl=yes
server=update6.dedyn.io
login=michaelloercher.dedyn.io
password=mypassword
myurl

but I also need to run crontab to get valid connection established what is wrong in my configuration?

0 */2 * * * ddclient -force >/dev/null 2>&1

What is the problem, it does not start?
In their docs they show a command to start as daemon, which you could add.
On their GitHub I also saw a example config for a systems service.

Also, it’s recommended to use full absolute paths in crontab, see the example in link above.

It’s running but the IP get sometimes not updated

You can try to start it with -debug flag to get more info, but the best woud be to ask the devs of ddclient:
