in jupyterhub_config.py have you enabled the Authenticator with the line:
c.JupyterHub.authenticator_class = 'ltiauthenticator.LTIAuthenticator'
I assume jupyter.univexemple.com resolves to 127.0.0.1
are you loading the custom jupyterhub_config.py via the '-f' argument?
Is your web server configured for ssl? would that already be running on
port 443 on 127.0.0.1?
Regards.
