Yubico YubiKey 5C Nano doesn't work in Management Console

Hello.

I'm quite puzzled about this issue. I Have a Yubico YubiKey 5C Nano, which is listed as one of the supported devices for AWS. My YubiKey works on other websites, but I cannot register my YubiKey for MFA within AWS IAM for my account.

I've tried registering my YubiKey using Chrome, Safari and Firefox, without success. As mentioned, my key works fine on other sites - and I'd really like for this key to work with AWS as well.

Might anyone know how I can proceed?
