Nginx upload module (v 2.2.0) :: 502 Bad Gateway

[Piotr Polok]

HI,

I have compiled newest version of nginx (nginx/1.1.1) with nginx upload 
module (v 2.2.0), also the example config (nginx.conf) was copied from 
https://github.com/vkholodkov/nginx-upload-module into nginx direcoty. 
The html form is also copied from this location. So the installation and 
configuration is oryginal now without any changes.

I'm getting some errors while uploading the file;

The html form: '502 Bad Gateway';

The nginx error.log (/usr/local/nginx/logs/error.log):

------
2011/09/05 08:35:15 [error] 21161#0: *6 connect() failed (111: 
Connection refused) while connecting to upstream, client: 192.168.0.165, 
server: , request: "POST /upload HTTP/1.1", upstream: 
"http://127.0.0.1:8080/upload", host: "192.168.0.127", referrer: 
"http://192.168.0.127/http/upload.html"
------

Maybe it's a problem of my wrong understanding how does it works, I do 
not understand why in this example config the proxy_pass is going 
through local 8080 port but the server in this configuration is not 
listening on such port.

Please help.
