[galaxy-dev] Nginx Config

26 Nov 2014

      Hi,

I am trying to setup a local production Galaxy running on Ubuntu,
Nginx, PostgreSQL, and ProFTD.

When visiting http://localhost, "502 Bad Gateway" is returned.
Visiting https://localhost returns "unable to connect". I was
expecting to see the Galaxy website instead.

My Nginx configuration file is included below. Thank you for your help.
