I was having the same issue - this fix worked for me.
Just like @Hentai, I did everything as root - and made sure to restart Nginx when appropriate.
Heh, I guess I did assume that nginx and NodeBB were on the same server 
@julian I'm around, just trying to figure out my own apache configuration for what it's worth
@julian Yeah, they were on the same server 
, and thank you for your warm help 
@Hentai, glad to hear it was resolved.
@julian, they're on the same server, so I have no idea what the issue was. Only variation from the docs was running as root, not just a sudo user.
I'm just now getting to play with the platform in full swing, and it certainly seems promising. It has all the important aspects of a social experience, without the clutter.
I have only a few suggestions, but I hear they drop in 0.5, so I can't wait 
Oddly enough this fixed it for me to, hopefully those searching for a** fix to nginx 502 bad gateway with NodeBB** come across this solution as it took me some time. I didn't think it would work because it was on the same server but it did.

@EpicIM_Inc Can you run ifconfig on your server? Is the loopback adapter not set up?
