DuckDns Let' Encrypt wont' encrypt


I use the duckdns-letsencrypt-addon but it’s not encrypted.
So when I try to open nothing happens.
Http works fine (without encryption).

I use a ipv6 hassio and maybe thats the problem?

I already opened the ports 8123, 443, 80 over the option “IPv6 Host Exposure” in my router.

The log-files looking good:

6-init] making user provided files available at /var/run/s6/etc...exited 0.
[s6-init] ensuring user provided files have correct perms...exited 0.
[fix-attrs.d] applying ownership & permissions fixes...
[fix-attrs.d] done.
[cont-init.d] executing container initialization scripts...
[cont-init.d] done.
[services.d] starting services
[services.d] done.

Here is my config file:

aliases: []
  accept_terms: true
  algo: secp384r1
  certfile: fullchain.pem
  keyfile: privkey.pem
seconds: 300
token: xxx

Thank you for help!

Try this video. Sounds like you need to get a few things changed on port forwarding. You should be able to call and have it connect.

You also have to configure HA to use the certificates:

  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem

Thank you, I totally forgot it!
Now it works fine.
