Nginx what is the right configuration for Socket.io?
Solution 1:
Here is an example NGINX configuration block for webscokets. Notice how the connection is upgraded if a valid websocket connection is made to the end point http://127.0.0.1:8080/wsapp
More at NGINX as a WebSocket Proxy
location /wsapp {
proxy_pass http://127.0.0.1:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Host $host;
proxy_hide_header 'Access-Control-Allow-Origin';
}
