App Name and APP Password

I use Nextclout 18 on an Ubuntu 18.04 server and use Fail2Ban and TOTP 2 factor login. I have multiple users.
Unfortunately, the login via the created “app name” and with the user name and the app password does not work. It always happens that the username or password are wrong.
For one user, it works with IOS CalDav.

  1. Under Settings -> Security -> “App Name” I put e.g. “IPhoneFelix” and click on “create new app password”
  2. I copy the username and password that is then displayed
  3. When I try to log in via Iphone CalDav or another app or browser, the data is incorrect.
  4. I also clicked “Done”

What am I doing wrong or is this a bug?
