I am using nginx 1.4.1 and I am trying to configure it with to work with socket.io websockets. I think I have done it correctly since I see a 'handshake authorized', but after a few seconds socket.io starts using xhr-polling, jsonp-polling and couldn't work.
My node.js express app runs on localhost:3002. And I use nginx to reverse proxy to this app. Socket.io is also listening on the same port.
I tried to follow many guides in SO and elsewhere but I just couldn't get this to work. Need some help from you experts. I've also placed by error log in here, not sure if it will help.
nginx.conf:
upstream instaneous {
server 127.0.0.1:3002;
}
server {
listen 80;
server_name instaneous.pin.gs;
access_log logs/instaneous.access.log;
error_log logs/instaneous.error.log;
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_pass http://instaneous;
proxy_redirect off;
# enables WS support
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
}
