Hi,
I moved from my Raspberry PI 3 to a brand new PI 4.
I restored a Snapshot, most things are working but I had to uninstall and reinstall some Plugins (for example Mosquitto).
But now, my HASS won’t connect to my MQTT broker I always get the following message:
Unable to connect to the MQTT broker: Connection Refused: not authorised.
All my other devices are working normaly (I can connect to the broker).
My HASS Username and Password is exactly the same like on the old PI3.
I would reset the credentials for the MQTT Integration but I configured the integration via GUI and not via config file… The only way would delete the MQTT integration and recreate them. But then I would loose all my MQTT entities…
Is there any way to solve my problem?

Edit:
In my Mosquitto log I get many of those messages:
