I\'ve just installed a Ubuntu 12.04 server and nginx 1.2.7, removed default from sites-enabled and added my own file into sites-available and symli
I ran into the same problem, I got a Failed to load resource: net::ERR_CONNECTION_REFUSED error when connecting over HTTP, but fine over HTTPS. Ran netstat -tulpn and saw nginx not binding to port 80 for IPv4. Done everything described here. Turned out to be something very stupid:
Make sure the sites-available file with the default_server is actually enabled.
Hope this saved some other poor idiot out there some time.
