As the title suggests, I am no longer able to authenticate to the core_mosquitto server. It doesn’t look like the addon has been updated in the last couple of days. The only thing I think I did update was the HA OS.
I even created a new user and tried to connect via MQTT Explorer.
Am I missing something?
edit: I manually created a user inside the addon and it works. So it seems something is broken between Mosquitto and HA.
