I'm having this Connection error deploying my django app on Heroku:
ConnectionError at /admin/login/
HTTPConnectionPool(host='localhost', port=8000): Max retries exceeded with url: /authentication/login/ (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))
Exception Value:
HTTPConnectionPool(host='localhost', port=8000): Max retries exceeded with url: /authentication/login/ (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))
It seems that the app doesn't find the url where the login must be done but the file setings.py is correct:
