Question

The dreaded 502 error

I use Pycharm while creating a website using Django/python. The website works as expected on localhost through Pycharm, so I decided to try and move it to a webserver. I followed this tutorial multiple times but still get the 502 error. https://www.youtube.com/watch?v=Y-CT_l1dnVU&t=609s

Ngnix error reads:

2017/03/01 04:53:33 [error] 2232#2232: *48 connect() to unix:/home/django/gunicorn.socket failed (111: Connection refused) while connecting to upstream, client: *client IP*, server: _, request: "GET / HTTP/1.1", upstream: "http://unix:/home/django/gunicorn.socket:/", host: "*host IP*"

and Gunicorn error reads:

if it matters, the file system is:

*home
   *Django
      *Django_project
          *Django_project
             *wsgi.py
             *init.py
             *settings.py
             *urls.py
          *ueba
             *migrations (folder)
             *static (folder)
             *templates (folder)

             *tests.py
             *views.py
             *models.py

I feel like I’ve tried multiple suggestions and variations of configs for both the ngnix and gunicorn through docs on OD but still haven’t nailed it out.

Let me know if I need to provide more docs, thanks!

You only have to look at your Django project (or Gunicorn more specifically). This has nothing to do with Nginx, right now at least, since you can’t even run Gunicorn. Try starting it with debug level, in hope to get a better error message than “exit-code”: gunicorn_django -b 127.0.0.1:8000 --settings=myapp.settings.dev --debug --log-level debug Modify the command, so it fits your project, just leave the --debug --log-level debug
