“Out of Home” means that the TV IP address does not match the IP address that your router has. It can happen if you clone the MAC address in your router, or if you leave your modem and router unplugged for 10 minutes or longer, or naturally over time; for DSL internet your IP address may change every 2-6 weeks naturally.
You can fix this error by giving us a call at 1-866-434-5888 to have your IP address updated, or by signing out and signing back in to Start TV.
