I have a simple MQTT-IN, with a function behind it. So far everything works as well.
But when I change the function and deploy everything, the MQTT connection breaks and does not come back.
If I now change the function again (even if it is only an inserted space), deploy everything again, so the connection is re-established.
MQTT connection is Qs0, no TLS etc.
Any idea what this could be due to (current NodeRed version) or where I could look further?
