help with proxy/port issue

[fredzannarbor]

Hi,

I'm trying to get the sandbox running on an AWS ubuntu dev server that I have and I am running into a problem because this server is already using ports 5000, 5001, 5007, and 5008 for other flask/gunicorn applications. I can't quite figure out how to set things up to use a different port, say 5009. THe key variables seem to be the proxy value set in package.json and the port & host values optionally provided in demo_web_app.py at app(run). Which of them needs to be set to the new port value?
