Weirdness with Django 404 page?

Question

Django

I decided to create a custom page for errors in Django
in the settings I wrote

DEBUG = False
ALLOWED_HOSTS = ["127.0.0.1"]

In the main urls (there is also a separate blog application, with its own urls, it also stores templates and statics for 404 pages, as well as a view that displays all this)

from django.conf.urls import handler400, handler403, handler404, handler500

and under urlpatterns I wrote this

handler400 = 'blog.views.page_not_found'
handler403 = 'blog.views.page_not_found'
handler404 = 'blog.views.page_not_found'
handler500 = 'blog.views.page_not_found'

well and such views

def page_not_found(request):
  return render(request, '404.html')

The strange thing is that
in my error page (which is displayed the same for all errors), bootstrap styles and a picture are connected,
I added the picture to the project a day ago, but the joke is that django sees and displays only old files, for example, bootstrap was from the very beginning and it connects or if I display the old images too, anything I add to the images or styles folder is not displayed and django does not see it, although it is there, what the hell? But if you connect something external, load a picture from the Internet, then everything is OK
