connecting to remote Python

Can I enter an IP address other than localhost? I do not see a host option in the Gateway, only a port. Maybe I'm overlooking it...

I'm trying to connect from Python on my Mac to a NetBeans app on
my Windows machine.
I get:
Traceback (most recent call last):
File
"/Users/richard/PycharmProjects/py4jtest/callback_listener.py",
line 34, in <module>
gateway =
JavaGateway(callback_server_parameters=CallbackServerParameters(address='192.168.1.9'))

line 1733, in start_callback_server
self._callback_server.start()
File "/Library/Python/2.7/site-packages/py4j/java_gateway.py",
line 2044, in start
raise Py4JNetworkError(msg, e)
py4j.protocol.Py4JNetworkError: An error occurred while trying to
start the callback server (192.168.1.9:25334)
I would expect maybe some more info, like a socket error
(connection refused, etc)
What could cause this?

Can you enable logging
(https://www.py4j.org/faq.html#how-to-turn-logging-on-off)?
It looks like the error occurred while binding to the ip/port. This
can happen if you had another py4j instance running or if you have a
restrictive firewall that blocks port binding.
