I'm sorry to hear you are having trouble viewing your Slingbox while away from home. Without being at the home location it is hard to tell what exactly is causing the error message. There is a possibility if your power went out that it interfered with the connection of the Slingbox. Is there a way someone could contact us from the home location so we could troubleshoot the issue? Please check out our Contact Sling Media link below:
Have a great day!
