Fetching static files failed with 404 in nginx
You should use alias instead of root. root appends the trailing URL parts to your local path (e.g. http://test.ndd/trailing/part, it will add /trailing/part to your local path). Instead of that, alias does exactly what you want: when http://test.ndd/static/ is requested, /static is mapped to your alias exactly, without appending static again.
For example:
location /static { alias /var/www/django/ecerp/erp/static/;}And if file /var/www/django/ecerp/erp/static/foo.html exists then going to /static/foo.html will return its contents.
TL;DR - you should check your files permissions
Stumbled upon this question and I was already using alias instead of root, so while the existing answer was up to the point, the following could be useful to others.
In my case, the solution to the same symptoms turned out to be the files in static/ having root as owner.
A simple chown www-data:www-data . solved the problem, and no more 404.
