SSL not working

Thanks a lot, this was exactly my issue!

Thanks it help me out

These are my configuration.yaml lines:

http:
base_url: https://ottoha.duckdns.org:8123
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem

If i try to connect to the duckdns domain from inside the lan or from outside (using a phone with wifi off) this is what i get:

Il sito non può fornire una connessione protetta
ottoha.duckdns.org ha inviato una risposta non valida.

  • [Prova a eseguire lo strumento Diagnostica di rete Windows](javascript:diagnoseErrors()).
    ERR_SSL_PROTOCOL_ERROR

I’m novice with HA, is there anyone who would put me on the right track? THANKS

Ugh, I didnt know YAML worked like that. Thanks for the solution.

I have been staring at this for days even weeks. Thanks so much for putting in your solution I had an extra space in front of my entire http section, and now it works!!! Thank you thank you thank you!!!

Could it be that the config has changed over these past months. I’m a new user and that ssl_certificate property gives me errors when validating the configuration.yaml.
