Having issues to connect to MQTT using the App. When I disable debug mode on my Nuki 3 Pro I see the following in my mosquitto log: I provided User and Password
2023-03-21 16:01:07: New connection from 172.20.1.99:52438 on port 1883.
error: received null username or password for unpwd check
When I enable debug mode I only get an error message within the app. Hostname could not be resolved ?? I use an IP address.
