Here is my nginx proxy that I use in production for a Socket.IO server:

location /socket.io {
        proxy_pass http://localhost:8890;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
}

I have this working for a year, already. Hope it helps.
