No connected status in node-red addon

Hi. I am running homeassistant and installed node-red and imported some flows from another node-red instance.
Ich hab some KNX and MQTT nodes which do not show connected ord disconnected in this installation.
In my previous installation of node-red which was done with docker there was no problem.
I am currently running HA 2025.2.5 on HAOS 14.2 .
The node-red version of the addon is 19.0.2 .

Each of these have their own configuration nodes, you will need to reconfigure them. I don’t use knx but it should be similar to mqtt. Open any mqtt node and edit the server.
