Static files like js and css have nothing to do with fastcgi.
However, since the file is in /admin/assets/569a8b41/css, but your conf has /app/backend/webas the document root, this will never be found, and you will always get 404, since you are asking nginx to look for /app/backend/web/admin/assets/569a8b41/css/bootstrap.cssone that does not exist.
