You get a 721 error if:

• The channel you’re trying to watch isn’t included in your subscription package
• Your receiver isn’t getting the programming info for this channel

Check your channel lineup for your package. If the channel isn’t included, learn how to upgrade or change your package.

If you subscribe to the channel and the error still displays, refreshing your receiver may fix it by reauthorizing your service.
