Upload media files django nginx

I’m trying to upload media files on the server but can’t figure out how to do it. I have no problem accessing my media files, but can’t upload any.

Here is what I’ve tried:

server {
    listen 80;
    server_name ****;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/joseph/hacka;
    }
    location /media/ {
        root /home/joseph/hacka;
    }
    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

In my settings.py, I have :

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

Please help me if you know the answer to my problem.
