add-machine command stuck

I created a manual cloud and made the bootstrap.

My environment is composed by machine with juju client connected to internet through a proxy and a controller machine without any internet connection, plus other machine without internet connection too.

I am following [Installing Charmed Kubernetes on Existing Machines | Ubuntu] (https://ubuntu.com/kubernetes/docs/install-existing) guide but I stuck at this step:

juju add-machine ssh:user@kube1

where the logs stay blocked here:

15:30:14 INFO  juju.cmd supercommand.go:56 running juju [3.5.4 31b4b0914740b84ad8166993635ac797a44276de gc go1.23.1]

15:30:15 DEBUG juju.api apiclient.go:689 looked up controller.localdomain -> [10.112.112.133]

In the meanwhile the controller logs report this connectivity error but is normal because there is no internet connection:

what step I miss?

I think the issue is relatedy with controller connectivity with internet, because I found exception like the following:
