nginx/0.8.54 - 502 Bad Gateway

[nginxn00b]

>>Did you try to just have your nginx listen on port 80 and see if it
works ?

Yes, I did. It is not working. I need to whitelist my IP and for that I
have to do some more paperwork. I'm in China. But my Chinese hosting
company said I should use Socket (Socks?), but I don't know what they
mean by that. My solution was to use another port (like port 81) and
forward the traffic then. Any other solutions possible?
