gzip not working in Django with Whitenoise

Question

I have a Django website deployed on Heroku, using Whitenoise for serving static files.

The static files work fine but Gzip is not working according to various websites that I used to test it (including google tools).

this is the code in my production settings files:

DATABASES['default'] = dj_database_url.config()


SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

ALLOWED_HOSTS = ['*']

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

My static files configuration:

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

STATIC_URL = '/static/'
STATIC_ROOT = 'staticfiles'

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
)

my wsgi.py file

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "sikumim.settings")

application = get_wsgi_application()

#HEROKU DEPLOYMENT

from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)

what could be the cause?

I ran a few commands suggested in the comments, looks like gzip isn't working:

WhiteNoise only enabled gzip for your static files, not for your entire site, so you need to check one of your static files e.g

curl -I -H "Accept-Encoding: gzip" http://www.sikumia.co.il/static/some-file.css
