nginx config:

upstream app_yourdomain {     server 127.0.0.1:3000; }  # nginx server instance server {     listen 80;     server_name mydomain.com;      # pass request node.js server correct headers , more can added, see nginx config options     location / {       proxy_set_header x-real-ip $remote_addr;       proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;       proxy_set_header host $http_host;       proxy_set_header x-nginx-proxy true;       proxy_http_version 1.1;       proxy_set_header upgrade $http_upgrade;       proxy_set_header connection "upgrade";        tcp_nodelay on;       proxy_pass http://app_yourdomain/;       proxy_redirect off;     }  }

socket.io running in 127.0.0.1:3000.

are running new enough version of nginx? websocket support introduced in nginx version 1.3.13. nginx -v see version have. see https://chrislea.com/2013/02/23/proxying-websockets-with-nginx/
