title: *13 upstream prematurely closed connection while reading response header from upstream
body: <p>I am configuring for 1st time and getting this error.
  Nginx site-enabled config is as follows:</p>
  
  <pre><code>#tream component nginx needs to connect to
   upstream django1 {
  #server 127.0.0.1:8001; # for a web port socket (we'll use this first)
  server unix:///run/uwsgi/app/apps/sokcet.B;
   }
  
  # configuration of the server
  server {
  
  # the port your site will be served on
  listen 9000;
  
  # the domain name it will serve for
  server_name xxx.xxx.xx.xxx; # substitute your machine's IP address or FQDN
  charset     utf-8;
  
  # max upload size
  client_max_body_size 75M;   # adjust to taste
  
  # Django media
  #location /media  {
  #    alias /path/to/your/mysite/media;  # your Django project's media files - amend as required
  #}
  
  #location /static {
  #    alias /path/to/your/mysite/static; # your Django project's static files - amend as required
  #}
  
  # Finally, send all non-media requests to the Django server.
  location / {
      uwsgi_pass  django1;
      include     /etc/nginx/uwsgi_params; # the uwsgi_params file you installed
      uwsgi_read_timeout 1800;
      uwsgi_send_timeout 600;
      proxy_read_timeout 600;
  }
  }
  </code></pre>
  
  <p>Uwsgi is running but nginx is giving this error.
  So kindly tell me what is the issue in my configuration.</p>
