i can access flask app directly the port 8080 though then through nginx reverse proxy I get an error

Error: 2014/11/28 01:02:16 [error] 2501#0: *4 upstream prematurely closed connection while reading response header from upstream, client: 75.64.105.189, server: xxx.yyy.com.au, request: "GET / HTTP/1.1", upstream: "uwsgi://127.0.0.1:8080", host: "xxx.yyy.com.au"

Calling uwsgi in a virtual env using the following

cd /home/ec2-user/prod_demo && /home/ec2-user/venv/bin/uwsgi --socket :8080 --wsgi-file /home/ec2-user/prod_demo/manage.py --callable app --processes 4 --threads 2 --stats :18080 --protocol=http &

seems to be working now after changing to the uwsgi ini config format instead of the cmd line

uwsgi.ini

[uwsgi]
socket = :8080
chdir = /home/ec2-user/prod_demo
master = True
venv = /home/ec2-user/venv
callable = app
wsgi-file = /home/ec2-user/prod_demo/manage.py
enable-threads = True

calling uwsgi.ini in shell / upstart (hopefully)

/home/ec2-user/venv/bin/uwsgi --ini uwsgi.ini
