ERR_HTTP2_PROTOCOL_ERROR loading admin pages in Django
I've started to get errors loading some pages in Django admin (with Grappelli): net::ERR_HTTP2_PROTOCOL_ERROR 200 It appears in chromium browsers console. These pages never load. For some time firefox has served this pages well, but today I've got the admin page which has been loaded partially, disrupted in the middle of inline forms, with this in the console: Layout was forced before the page was fully loaded. If stylesheets are not yet loaded this may cause a flash of unstyled content. I'm not even sure if the problem is with Django, because everything is ok on the dev server and the problem occurs with the production server (Nginx). I've already tried solutions from here with no result. But since the problem somehow connected with Django admin pages, how can I investigate it? -

Django + React: React "frontend" Django app vs. React scripts embedded in Django templates?
I am trying to understand how to best structure my Django-React project to increase readability and maintainability for the future.

Which alternative would be better for what particular context and why? -

Images I upload on the admin console are not served
This is being a bit confusing for me. If I set DEBUG=True run python manage.py runserver on VSC, I can access http://127.0.0.1:8000/admin, log in and upload a new photo that will be displayed when I access portifolio.html among the other photos that were previously updated. These photos are saved on BASE_DIR/media/images. However, when DEBUG=False, the previously shown images are not found anymore (404 error on console). I read online that I should use Whitenoise when serving static files on Django while on production and installed it. Still, I get the same behavior. When I run python manage.py collecstatic, the files located on BASE_DIR/django_app/static are copied to BASE_DIR/static and the media folder remains unchanged. settings.py DEBUG = False INSTALLED_APPS = [ 'whitenoise.runserver_nostatic', 'users.apps.UsersConfig', ... ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', ... ] SITE_ROOT = os.path.dirname(os.path.realpath(__file__)) STATIC_ROOT = os.path.join(BASE_DIR,'static') STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(SITE_ROOT,'static/'), ) STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') models.py class ImageModel(models.Model): image = models.ImageField(upload_to='images/') url = models.CharField(max_length=100,default='abcdefg') def get_url(self): return self.url def __str__(self): return self.url views.py def index(request): context = { "images": ImageModel.objects.all() } return render(request,'blog/index.html',context) url.py urlpatterns = [ path('admin/', admin.site.urls), ... ] urlpatterns += static(settings.STATIC_URL, document_root = settings.STATIC_URL) urlpatterns += static(settings.MEDIA_URL, … -
