MQTT disconnects

It is entirely possible that I have a remnant of an old topic

Then this could be a solution:

Error starting broker connection

check please the contents of the following file: /var/lib/openhab2/config/org/openhab/mqtt.config if they correspond to the settings that you have in /etc/openhab2/services/mqtt.cfg If not, shutdown OH2, delete the mqtt.config (not the mqtt.cfg) and then restart OH2 Now, for the other issue: can you post the contents of your /etc/mosquitto/mosquitto.conf
