CONTAP-706216: WebAuthn MFA login fails with WEBAUTHN_CHALLENGE_VERIFY_FAILED after 2-3 successful authentications
Issue
When using WebAuthn (FIDO2 / Yubikey) as the multi-factor authentication method for ONTAP System Manager / REST API login, the first 2-3 authentications succeed. After that, subsequent login attempts fail with the error WEBAUTHN_CHALLENGE_VERIFY_FAILED in sysmgr.log even though the security key returns the correct challenge response. The user is unable to log in until the condition is cleared on the node.
