Apache SSL proxy with JHUB

Hi everyone,

I am supposed to deploy JupyterHub and some others application on a distant server.

To do that, I put an Apache Proxy server and I rewrite requests, example :

  ProxyPass /jhub/
  ProxyPassReverse /jhub/ 

Everything is ok without SSL but when I start with HTTPS something goes wrong.
I can reach the Jhub authentication page, but, when I log in, it tells me that the connection is not secure.

SSL is activated at the level of Apache server and JHub is started without any SSL parameter.
Certificate and key have been generated with OpenSSL for testing purpose (not signed by CA).
Perhaps, the problem is here ? JHub can not authenticate the Apache Certificate ?

Thanks for your help.
