Redirect to login page with middleware is causing 'too many redirects" issue

Question

What I want is redirect users to login page if they aren't authenticated. I made a middleware but the redirect is not working. Could someone give me a help?

My urls:

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('contas/', include('django.contrib.auth.urls'), name='login'),  # I want call this
    path('', include('apps.props.urls'))
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

my middleware.py

from django.http import HttpResponseRedirect
from django.urls import reverse


class AuthRequiredMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        if not request.user.is_authenticated:
            return HttpResponseRedirect(reverse('login'))  # Here I call login
        response = self.get_response(request)
        return response

and finally, my settings.py

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'middleware.AuthRequiredMiddleware',  # Registering middleware
]

What I am getting is this page with "too many redirects"

Thans to @Melvyn and @Onsem comments I have improved my code. Here is one solution (We just need to be careful with files in media folder, they are accessed as AnonymousUser):

from django.http import HttpResponseRedirect
from django.urls import reverse


class AuthRequiredMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        # Here I call login if not authenticated and request is not login page
        if not request.user.is_authenticated and request.path != reverse('login'):
            return HttpResponseRedirect(reverse('login'))  
        response = self.get_response(request)
        return response
