Need help to setup MQTT Binding on OH2

[Dim (Angelos)]

@DonStefano

uninstalled the MQTT action. Suddenly the MQTT binding started to work again.

unfortunately, there is still an open issue on this: [MQTT with MQTT Action] MQTT Binding will not connect with action installed · Issue #5038 · openhab/openhab1-addons · GitHub

With MQTTv2 we won’t have this problem anymore
