Try changing this to proxy_pass http://huoshaolin.com:4567/;

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.

[julian]

Heh, I guess I did assume that nginx and NodeBB were on the same server

[Hentai]

@Tanner @Albus

Oh ! it really works !!! Thank you very much

[julian]

Haha @Tanner @Albus, you guys should hang around more often

[Tanner]

@julian I'm around, just trying to figure out my own apache configuration for what it's worth

[Hentai]

@julian Yeah, they were on the same server , and thank you for your warm help

[A Former User]

@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.

proxy_pass http://mydomain.com:4567/;

[julian]

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