Does "ssh ubuntu at 10.115.0.2" work

This command is using your localhost to do the initial connection. The
error can be from your localhost, not from the
state-server/controller.

Once your *client* juju has entered the machine it checks that jujud
is not installed, the machine can connection to the
state-server/controller over the private address, and there is an
ubuntu user. Your juju client will provision the machine. Once
complete, the machine will talk to the state-server/controller
normally.
