I'm trying to run a Flask application using a ubuntu 12.04 server with nginx and uWSGI however after starting the server, specifying the wsgi.ini file and then starting nginx, I try to access the page but I get a 502 bad gateway error with nginx. I know that it is an issue with the flask application and uWSGI. I checked the uWSGI logs and found this:
*** Starting uWSGI 2.0.11.1 (64bit) on [Thu Sep 17 19:38:03 2015] ***

I found this question's top answer but saw received the same error. If it is something to do with PYTHONHOME, I'm following this guide and it states:
The $PYTHONPATH variable seems to get unset randomly, and causes errors for later steps. To avoid this, add the following line to the top of your ~/.bashrc file:
export PYTHONPATH='/usr/lib/python2.7:/usr/lib/python2.7/plat-x86_64-linux-gnu:/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/lib-old:/usr/lib/python2.7/lib-dynload:/usr/local/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages/PILcompat'
So what could be the issue? Is it PYTHONHOME or another factor affecting it? Thanks.
Edit:
My uwsgi.ini:
[uwsgi]
home = /home/ubuntu/myapp
wsgi-file = %(home)/run.py
socket = 127.0.0.1:5000
callable = app
module = app
pythonpath = %(home)
daemonize = %(home)/myapp.log
pidfile = %(home)/myapp.pid
To run it, I use uwsgi uwsgi.ini.
