Connection Error

[reasg]

Hello,
In a building with 4 ComfoAir Q (350|600), I was able to integrate three into Homeassistant. Great software!

There is an exception with the 4th device:
aiocomfoconnect.exceptions.ComfoConnectNotAllowed: 0000000000311010800170b3d5426b1f -> 00000000000000000000000000000001: 083510052001
type: StartSessionConfirmType
result: NOT_ALLOWED

Is this a problem with the software or the device? And how can a connection be established?
