Reverse proxy web socket wss in Ngnix

If you want to reverse proxy the websocket for a domain to a URL in nginx on Ubuntu then you need to add the following section in the configuration file of your site:

      # WebSocket support
       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "upgrade";

Go to your /etc/nginx/sites-available/<yourdomain> file and add the above section there at the location where you want to redirect. The complete file will look like this:

server {

    server_name yourdomain.com;


   location / {
  
      proxy_pass https://127.0.0.1:8080;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      # WebSocket support
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
   }


}
