Hi,
Second question of the day. I feel very dumb xD
Well then, I get 502 Bad gateway. I don’t know nginx that well.
I have followed [This guide](https://meta.discourse.org/t/running-other-websites-on-the-same-machine-as-discourse/17247)
Cheers!

As that guide says

If you aren’t familiar with nginx, docker and web hosting in general, please stay on the official guide.

Well i do know a bit of nginx, and I use it regularly. But I don’t know the errors of nginx well. I don’t really see any obvious errors.

502 means your Discourse instance is not starting / started / running.

Hi, After some investigation i found the `nginx.http.sock` file never gets created
Not when rebuilding, or whatever.
How can i fix this?
With kind regards,

After even more investigation i now found the issues (I think) now I get this:
```plaintext
Errno::ENOENT: No such file or directory @ rb_sysopen - /etc/nginx/conf.d/discourse.conf
Location of failure: /pups/lib/pups/replace_command.rb:8:in `read'

Any ideas @Falco ? Because we really do not know.
