This is problematic for the Konnected devices when used with the LetsEncrypt certificates generated by the DuckDNS addon.
II would rather change this with : it’s just because the Konnected product is badly designed.
-Integration to GOOGLE Home can work with an SSL URL.
-HA DuckDNs add-on works as charm to provide SSL certificate.
and then Konnected Alarm Panel does not support SSL
Add-on NGIX on top of DUCKDns is just messing up HA (at least when using setup describe in the link above)
Loosing patience with this product !
