Mosquitto broker authentication failing
(infosec.pub)
Not sure why but my mqtt broker I installed from the addons is not working. Any help here should be nice. When I look at the settings the password says "password_not_changed" wuth username "homeassistant".
you could add a new user ...depending on your unknown setup. you could try sending mqtt test packages from your terminal or any mqtt tool. that would narrow down the problem a lot.
