"response code: 502" using socket.io and nginx 1.4.x (stable) with proxy_pass -


i trying make running app (using socket.io) under nginx, , websocket connection 'ws://...' failed: unexpected response code: 502 error on server side. have read nginx suport websockets since v.1.3 have upgrade nginx v1.4.1 (stable).

here conf:

server {        listen 80;        server_name website.com;          location / {           proxy_pass    http://127.0.0.1:3000;           proxy_http_version 1.1;           proxy_set_header upgrade $http_upgrade;           proxy_set_header connection "upgrade";           access_log    /var/log/nginx/website/access.log;           error_log    /var/log/nginx/website/error.log;         } }

update:

i have can reach app (so listen port 3000) , socket.io working unless error, in cases, emit call desn't send arguments undefined.

what missing here avoid error?

i have found avoid error:

io.set('transports', ['xhr-polling']);

so socket.io ajax calls, job way more slowly, if has real key issue still interested!
