title: Django Channels doesn't detect WebSocket request with NGINX
body: <p>I am deploying a website on AWS. Everything works fine for HTTP and HTTPS. I am passing all requests to Daphne. However, incoming WebSocket connections are treated as HTTP requests by Django. I am guessing there is some header that isn't set in Nginx, but I have copied a lot of my Nginx config from tutorials.
  Nginx Config:</p>
  <pre><code>upstream django {
          server 127.0.0.1:9000;
  }
  
  
  server {
          listen 80;
  
          server_name 18.130.130.126;
  
          return 301 https://$host$request_uri;
  }
  
  server {
          listen 443 ssl;
  
          server_name 18.130.130.126;
  
          ssl_certificate /etc/nginx/certificate/certificate.crt;
          ssl_certificate_key /etc/nginx/certificate/private.key;
  
          proxy_http_version 1.1;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection &quot;upgrade&quot;;
  
          proxy_redirect off;
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Host $server_name;
  
  
          location / {
                  include proxy_params;
                  proxy_pass http://django;
          }
  }
  </code></pre>
  <p>Daphne is bonded to 0.0.0.0:9000. Channels have a very basic setup. A ProtocolTypeRouter, with AuthMiddlewareStack and then URLRouter, as shown on the Channels tutorial. And then a Consumer class. I am using Redis for the channel layer, but that doesn't seem to be a problem. This is some data about the request on response from fiddler. The request headers say Upgrade to WebSocket, but it returns a 404 HTTP request, as it doesn't see it as a WebSocket request.<a href="https://i.stack.imgur.com/kg5Qc.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kg5Qc.jpg" alt="enter image description here" /></a></p>
  <p>Thanks for any help.</p>
