如何纠正 django 中的帐户激活错误

Question

I'm trying to click on an email activation link so as to activate a user account after submitting a registration form but I keep getting this error: The connection for this site is not secure; 127.0.0.1 sent an invalid response. The connection for this site is not secure; 127.0.0.1 sent an invalid response. . I ought to be redirected to the dashboard. Account is successfully created since the new user appears in the database but clicking on the activation link sent to the email throws back an error. I'm following a tutorial though, but I can't figure out why the problem occurs. url.py

urlpatterns = [
    path('activate/<slug:uidb64>/<slug:token>)/', views.account_activate, name='activate'),
    path('dashboard/', views.dashboard, name='dashboard')
]

templates

account-activation_email.html:

{% autoescape off %}
Great {{ user.user_name }}!
Please click on the link below to activate your account
https://{{ domain }}{% url 'account:activate' uidb64=uid token=token %}
{% endautoescape %}

Answer 1

After some research I found out that the error occurs because I was using https instead of http, since I'm using a local server.
