Adding HTTP stops HA fully starting

I have duck DNS setup and there are certificate files in /SSL
However adding the http: section to config stops HA fully restarting (using a Pi3b). The system is using all the latest versions,

  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  ip_ban_enabled: true
  login_attempts_threshold: 5

The log files has numerous entries like below.

I am not an expert in python so any help would be appreciated.
