Trying to activate SSL for appdaemon - any ideas on how?

I have appdaemon running here, I’m currently only using the dashboard part, but I would like to have it running via SSL, so I looked in the docs, and altered the config a bit, and now part of it looks like this:

appdaemon:
  disable_apps: 1
  threads: 10
  app_dir: /config/appdaemon/apps
  dash_ssl_certificate: /ssl/combined.pem
  dash_ssl_key: /ssl/domain.key

The certificate and key file are placed in /ssl
But after it restarts it is still not ssl encrypted. It does look like it doesn’t reply on port 5000 which is the api port though.
