How to fix django middleware infinite redirect?

Question

Django

Hello.
Initially, the task is to close the entire site from unauthorized users.
I'm trying to solve this writing my middleware, but I ran into an endless redirect when the condition is met.

The middleware class itself:

class LoginRequiredMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.

        login_path = '/account/login/'

        response = self.get_response(request)

        if not request.user.is_authenticated and request.path != login_path:
            return HttpResponseRedirect(reverse('account:user_login'))

        # Code to be executed for each request/response after
        # the view is called.

        return response

The view itself:

def user_login(request):
    if request.method == 'POST':
        form = LoginForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = authenticate(username=cd['username'], password=cd['password'])
            if user is not None:
                if user.is_active:
                    login(request, user)
                    return HttpResponse('Authenticated successfully')
                else:
                    return HttpResponse('Disabled account')
            else:
                return HttpResponse('Invalid login')
    else:
        form = LoginForm()
    return render(request, 'account/login.html', {'form': form})

url from account

urlpatterns = [
    path('login/', views.user_login, name='login'),
]

and project urls

urlpatterns = [
    path('admin/', admin.site.urls),
    path('travel/', include(('travel.urls', 'travel'), namespace='travel')),
    path('account/', include(('account.urls', 'account'), namespace='account'))
]

The middleware itself is connected to the last one in settings.py

As a result: I get an endless loop (302 in the console), nothing is returned to the face (the site did not respond)

What am I doing wrong and where to dig further?)
Thanks in advance to everyone!)

Debugging, from the simplest - add prints and use them to display the values ​​\u200b\u200bthat participate in the condition, before using debuggers, the same built-in pdb
PS well, such a check should be done before the view call, and not after.
