Fritz!Box 5590 Fiber integration

Hi there,
I am using a Fritz!Box 5590 Fibre. The Integration of the AVM Fritz!Smart Home was successfull. But the integration of AVM Fritz!Box Tools with the 5590 Fiber did not succeed. I got the error message:

Logger: homeassistant.config_entries
First occurred: 11:04:18 (2 occurrences) 
Last logged: 11:04:19

Config entry 'FRITZ!Box 5590' for fritz integration not ready yet: UPnPError: errorCode: 401 errorDescription: Invalid Action; Retrying in background

I know that the 5590 Fiber has not been tested yet (AVM FRITZ!SmartHome - Home Assistant). But as this device seems to be very similar to the 7590, I think it should work.

Of course I enabled TR-064 and UPnP.

Any suggestions? Or doas anybody know when the 5590 Fiber will be integrated/ tested?

Thanks in advance
