Why doesn't the original Django Nginx image open?

Question

Django

I ran into a problem that the server does not open the original image. Instead it says 403 nginx.
All images are output via:

{% load thumbnail %}
{% thumbnail image.image 800x800 crop %}

They open without problems and lie next to the original ones.
Sizes of the original from 800kb.
Why can this be so?

Answer 1

logs help a lot.

Answer 2

Try to clean up the sumbnails. Up to the toughest teams.
