django ERR_CONNECTION_REFUSED

Question

I'm trying django framework these days and I am facing this error described above.
I have an app in the project called products and it has views.py module with this code inside:
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello World")
and another file urls.py in the same directory with the following code:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index')
]
and also the root urls.py file in the project :
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('products/', include('products.urls')),
]
all of this as I checked from Django documentation should work but the result is ERR_CONNECTION_REFUSED when I try to access the directory using the server.
if you have any experience in Django, please help.
