Your ViewMedica embed is not allowed because the embedding domain (URL) does not match any of your account domains. Log in to your ViewMedica Account and update your URL to match this location. If you are testing your site on a staging server, you will need to enter the temporary domain and then update with the final domain for launch.
When you signed up, you registered On-Demand for use on a single, authorized domain. This error is shown when the On-Demand embed code is used on an unauthorized domain.
If your domain name has changed, update the domain in your Viewmedica.com account.
Under certain circumstances, the On-Demand player may be used on multiple domains.
