NGINX serve static files - django project has no styling

I managed to deploy my Django app but I can not pass the static files with Nginx. I have followed all the instructions for deploying to production. When I inspect the page all I see is empty static folder Can anyone spot the mistake?

Thanks a lot

nginx.conf

 10 upstream app_upstream {
  9     server app:8080;
  8 }

  6 server {
  5     listen 80;
  4     listen 443;
  1     server_name #######;
  2
  3     location /static/ {
  4         alias /static/;
  5     }
  6
  7     location /media/ {
  8         alias /media/;
  9     }

 11     location / {
 12         proxy_set_header Host $host;
 13         proxy_pass http://app_upstream;
 14     }
 15 }

settings.py

Error message when I docker-compose:

Having had a similar issue (but NOT using Docker), perhaps this might help.

If you have a static folder in your root project for project level static files, and if you also have a command to run python manage.py collectstatic --noinput in your docker-compose or Dockerfile, which not understanding Docker too well, I think you'd still need in production, then perhaps renaming the STATIC_URL and STATIC_ROOT in settings.py can help since that command will try to collect all static files from all your apps into one folder. Try something like this:

    STATIC_URL = '/staticfiles/'
    STATIC_ROOT = str(BASE_DIR.joinpath('staticfiles'))
    STATICFILES_DIRS = [str(BASE_DIR.joinpath('static'))]

Note that you would also have to update your Nginx file, i.e.,

    server {
            ...
            location /staticfiles/ {
            ...
           }
