Nginx cloudflare 502 bad gateway - php

Question

I'm using cloudflare. My site is working good but not loading any images, css files and js files.
My server details;
ubuntu 12.04
nginx/1.1.19
php5-fpm
mysql
You can check live here
Check with www and without www.
I think that problem is related to proxy (cloudflare)

A 502 gateway generally indicates a temporary issue in a datacenter and you should contact us if you see this.
Things that are helpful in the report:
Traceroute to the domain
And the output from: http://yourdomain.com/cdn-cgi/trace (replace yourdomain.com with your actual domain).
