Here's my output
host=None
exit_code=None
channel=None
exception=('Authentication error while connecting to %s:%s - %s', '10.201.64.106', 22, AuthenticationError('No authentication methods succeeded'))
encoding=utf-8
read_timeout=None

When the authentication fails, the host is empty, this time do not know is that ip failure

There is legacy API right now that generally works, but there should be a better versioned API for the server, that utilizes HTTP verbs better, we probably should revamp some configuration keys and response formats too.
