Nitrokey 3A NFC cannot be activated on Joomla

Hello all, I try to activate a Nitrokey 3A NFC on a fresh Joomla installation with Joomla 4.4.1/Win11/Firefox 120. I’m asked to enter the pin of the key, after that to press the button on the key and this now goes in an endless loop. What can be done?
Thanks for any help.
