Looks like the broker just isn’t running (which seems to match with the errors you’re getting [here](https://community.homey.app/t/mqtt-broker-stopped-working/73406/14)).

I got the broker to run. I can also connect to it with the MQTT explorere. (The log in the MQTT Broker is all zoomed in some how…)

In addition to the above, the Tasmota MQTT app is working, and I can control my lights now via the Tasmota MQTT. I guess this means that the Broker is working properly and that the issue is at the MQTT Client.

Good to hear it’s working again.

Over here still no progress.  
Broker is running, but clients can not connect to it die to not authorized.  
Tried all different settings.  
Mqtt cliënt also not much luck.

I do see in the broker log all devices trying to connect though.  
But no other response.

Mqtt explorer also not able to connect.  
It feels like something is configured somewhere on the background. Which prevents connections.

Clueless…

FOUND IT!!!

Stupid from my side. I configured all devices in a new MQTT topic structure. This wasn’t working for the tasmota devices.  
So nothing wrong with broker, as long as you are not using exotic MQTT topic structure I guess.  
just leave the full topic to %prefix%/%topic%/

Thnx for all helping directions! Sorry for my mistake.
