After searching a little bit deeper I found the following:

[MQTT not reconnecting on edit if only only one mqtt node using the config node #3927](https://discourse.nodered.org/t/mqtt-not-reconnecting-if-only-only-one-mqtt-node-using-it/69381)

This is a known bug and already fixed (hopefully will be released in the next version)

After adding a second MQTT node it is working as expected, MQTT connection is stable after deploying
