'Scheduled check for new software failed : Couldn't resolve host name (6)

I am trying to update new software for my Linux target device using "Eclipse Hawkbit" update server.

The Hawkbit server is launched on my "host" device and I have the rauc-hawkbit-updater daemon running on my "target" device.

It seems that I have a problem when setting the "hawkbit_server" value in my rauc-hawkbit-updater "config.conf" file.

As a result, the check for new software always fails and returns an error code (6) : Couldn't resolve host name.

My question is how to determine the right value of the Hawkbit update server "host name" ?

Thanks.
