Convert uWSGI HTTP server to work behind Nginx instead

I'm serving my app with uWSGI using uwsgi --http-socket 127.0.0.1:3031 -w app:app, which works when I go to 127.0.0.1:3031 in a browser. I want to use Nginx, so I told it to uwsgi_pass to that url, but now I get a 502 Bad Gateway error. How do I put uWSGI behind Nginx?

server {
    listen 8080;
    server_name 127.0.0.1;

    location / {
        uwsgi_pass 127.0.0.1:3031;
        include uwsgi_params;
    }

    location /static {
        alias /static/folder/location;
    }
}

2016/05/16 19:50:09 [error] 6810#0: *4 upstream prematurely closed
connection while reading response header from upstream, client:
127.0.0.1, server: 127.0.0.1, request: "GET / HTTP/1.1", upstream:

You can use http-socket between nginx and uWSGI. For example, if you launch your python app with uWSGI:

uwsgi --http-socket 127.0.0.1:3031 --wsgi-file application.py --callable app --processes 4 --threads 2 --stats 127.0.0.1:9191

Configure Nginx with:

location / {
    proxy_pass http://127.0.0.1:3031/;
}

Use socket, not http-socket.

uwsgi --socket 127.0.0.1:3031 -w app:app

http-socket makes uWSGI act like a web server that speaks HTTP, and is not correct if you're using Nginx, since it understands uWSGI directly.
