     You need to ensure that your Client ID has been authorized in the admin console of the enterprise you're trying to interact with. The steps to do this are mentioned in step #3 https://developer.box.com/docs/setting-up-a-jwt-app#section-step-3-grant-access-for-the-application-in-your-enterprise.
