Where is your MQTT broker running?
There is no system internal broker any more apparently:

MQTT System Broker no more selectable after upgarde to 3.3.0 M2 from M1

I have been using zigbee2Mqtt for years. When I moved openhab 3.1, I started to use the system MQTT Broker. In openhad 3.3.0.M1, it is still working. I did the upgrade to M2 and it doesnt anymore. If I uninstall the MQTT binding, re-install it and properly configure the system MQTT Broker, all my existing MQTT thing dont work amd if I try to change the bride, nothing selectable there.
