proxy_pass http://127.0.0.1:5000; 502 bad getway

(13: Permission denied) while connecting to upstream:[nginx]

I am working with configuring django project with nginx and gunicorn. While I am accessing my port gunicorn mysite.wsgi:application --bind=127.0.0.1:8001 in nginx server I am getting the following error in my error log file.

2014/05/30 11:59:42 [crit] 4075#0: *6 connect() to 127.0.0.1:8001 failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8001/", host: "localhost:8080"

My nginx.conf file

server {
    listen 8080;
    server_name localhost;
    access_log  /var/log/nginx/example.log;
    error_log /var/log/nginx/example.error.log;

    location / {
        proxy_pass http://127.0.0.1:8001;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $http_host;
    }
}

In the html page I am getting 502 Bad Gateway.

What mistake am I doing?

I had a similar issue getting Fedora 20, Nginx, Node.js, and Ghost (blog) to work. It turns out my issue was due to SELinux.

This should solve the problem:

setsebool -P httpd_can_network_connect 1

Details

I checked for errors in the SELinux logs:

sudo cat /var/log/audit/audit.log | grep nginx | grep denied

And found that running the following commands fixed my issue:

sudo cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M mynginx
sudo semodule -i mynginx.pp
