/static/css/style.css 404

Hi,
I'm trying to run the `Django` app
I can confirm that `/static/css/style.css` is being served when running the app using `./manage.py runserver`
but I've tried to run the app using `Gunicorn` and `Nginx` but it always gives me `404` and display the web app without any CSS/static content.
I've also tried `uWSGI` but still the same

Any thoughts?
