staticfiles в django + nginx + gunicorn + vps

У меня есть django проект, который я не могу развернуть на сервере
staticfiles не загружаются…
в Гугл Консоли для разработчиков: Status code at "Network": 403 Forbidden к моим staticfiles

/etc/nginx/sites-enabled/default

server {
    listen 80;
    server_name <site_domain>;
    access_log  /var/log/nginx/example.log;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /root/code/3p_site_new/;
    }

    location /media/ {
        root /root/code/3p_site_new/static/;
    }

    location / {
        proxy_pass http://127.0.0.1:8001;
        proxy_set_header Host $server_name;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

pythonpath = '/root/code/3p_site_new/3p_site_new'

limit_request_fields = 32000

Я пытают запустить сайт с помощью команды gunicorn -c "/root/code/3p_site_new/gunicorn_config.py" Site.wsgi
