NoReverseMatch: Reverse for 'session_security_ping' not found.

Hi there!
I love this app for my Django projects, but I have recently updated from Django 2.0 to Django 2.1 and now I'm getting this error:

Internal Server Error: /session_security/ping/
Traceback (most recent call last):

django.urls.exceptions.NoReverseMatch: Reverse for 'session_security_ping' not found. 'session_security_ping' is not a valid view function or pattern name.

Session security still seems to work, but getting this traceback in my logs is not ideal. I hope you can upgrade the compatibility to Django 2.1.
Thanks!

The url is defined here : https://github.com/yourlabs/django-session-security/blob/master/session_security/urls.py

Are you sure you have included them in your root urlconf ?

I do have them in my urls.py and the feature was actually working fine. I just kept seeing that traceback in my logs every time the warning would kick in. In the current project I'm working on I don't get the errors, so I guess it works... :)

Do you think this could be happening before django discovers urls ?
