I have a Yubikey version 5.2.7 and I can't generate any new certificates on yubikey manager app, which is weird since I have already generated two certs (on 9d slot) and they worked fine.

Now the following message pops up:

"Failed connecting to the YubiKey. Make sure the application has the required permissions."

However, I ran the app as admin but the same error is showing up.

I read the docs from yubico but it doesn't provide any further help.

I also tried to reset the key to factory settings, but it didn't change anything.

  • This looks more like a support call to the vendor. This is a specific issue with the app and not a security concern.
