bootstrap failed

[fengxia]

Hi Juju,

First time catch this bootstrap error.

Symptom is that it will hang on "Attempting to connect to....". I 
usually waited from 5-10min and Ctrl-c the process. This time I waited 
till it timed out.

Juju version: 2.3.1-xenial-amd64

What does this error mean? I have seen it a few times, sort of randomly 
however. So I never figured out what's the cause. Any pointer what I 
might be doing wrong?
