Why do I get the error 401 ERROR_AUTHENTICATION_FAILED (AUTHENTICATION_RESULT_PIN_IS_BLOCKED)?
Your admin_pin gets blocked after five unsuccessful authentication attempts.
In this case, you must reset your admin_pin.
Run the SIGN DE API V2 endpoint changeAdminPin request with your admin_puk and new_admin_pin.
