Fritzbox repeater 2440 discovered as new on every restart

I have a fritzbox2400 repeater and HA asks me to reconfigure with user and password every time the system is restarted but also after some days even without restarting home assitant.
Any idea what’s happening?

Same issue here, only with the FRITZ!Repeater 3000.

I have the same issue also, but only with newly added Fritz devices.
