Communication error when trying to unlock Nitrokey Storage

I suspect that my Nitrokey Storage is broken. I have been wearing it on my keychain for many years. I just wanted to confirm this with you before destroying it and buying a new device. Here are the symptoms:

  • When initially connecting the Nitrokey, it is detected normally
  • The first unlock attempt results in the message “Communication error. Please reinsert the device”.
  • Then the app enters a loop between “Device connected. Waiting for initialization” and “Nitrokey disconnected”
  • After reconnecting the device, it takes a long time (about a minute) until the device is shown in the app as connected again

I tried this on Linux and Windows, with similar results.

There are some other things that seem weird in the “About” window:

  • The PIN retry counter is shown as 77 for both admin and user, which seems too much
  • The “Encrypted volume” is shown as “Not active” even though I have been using it in the past
  • It also shows the message “New SD card found: Smartcard is inaccessible”

Is my Nitrokey broken?
