Some services restrict to only allow keys from certain vendors. For example, [Vanguard.com](http://Vanguard.com) supports only Yubikey, all other security keys are not permitted. For Azure AD, a handful of vendors are approved however any vendor key can be used by disabling ‘Enforce Attestation’ more info on that here - [Error adding Yubikey to Security Info - Microsoft Q&A](https://docs.microsoft.com/en-us/answers/questions/3908/error-adding-yubikey-to-security-info.html)

There may be a similar setting in the server you are using. Another thing to try would be to use a different browser such as Firefox to register the security key. Let me know if that works, if it does there is a possibly related issue here - [Cannot register to Microsoft Account - #13 by t11](https://onlykey.discourse.group/t/cannot-register-to-microsoft-account/205/13)
