I have an working project where over the MQTT-In node i subscribe to an Mosquitto Broker. But when i want to change to MQTT Version 5. On every other Subscriber it was working after just changing the version somewhere. But after changing it on the node it doesn't connect anymore. Do i have to change anything else to get it working or am I missing something?
Thanks!
