Nikon Z 6 WLAN connection possible?

Hello gphoto developers and users


I get a Wi-Fi P2P connection to the camera, can ping the it, get 
the ESSID ("Z_6_P<serial no>")
but when I call 'gphoto2 --summary' I get (only) this info:

and the camera stops the connection with the message: 'Unable to 
connect'

Any idea what I can do to get the WLAN connection working?
It would be very nice, if this works.-)
And yeah, the USB-connection works fine.
