Running HAOS 25.12.3, installed on Raspberry Pi 5
I’ve installed the addon AppDaemon, but it will not connect to the MQTT broker.
I’ve installed the core-mosquito MQTT broker addon using default configuration settings.
I’ve tried various settings of “Ignore Broker Certificate Validation” with no effect.
I can not change “Broker Certificate Validation” to auto as suggested somewhere.

Thanks.
