Before you begin
If you haven't already, try these steps to connect the Remote app and check the system requirements.
If the Remote app still won't connect to your iTunes library or Apple TV, or if it's never connected, try the steps below. After each step, see if the app can connect.
The Remote app is compatible with Apple TV (3rd generation or earlier). It isn't compatible with Apple TV (4th generation).
Check for software updates
On your computer, update to the latest version of iTunes.
Turn on Home Sharing
If you haven’t already, turn on Home Sharing in iTunes on your computer. Then turn on Home Sharing on your iOS device and your Apple TV.
Open iTunes on your computer
Make sure that your computer is on and awake and that iTunes is open. If iTunes is already open, quit and open it again.
iTunes must be open on your computer for Remote to connect with your iTunes library.
Connect your devices to the same Wi-Fi network
Your iPhone, iPad, or iPod touch needs to be on the same home or local network as your iTunes library or Apple TV.
If you have more than one Wi-Fi network, connect your iOS device to the same network as your computer or Apple TV.
Restart your router
Check your router’s user guide for steps. You might need to disconnect the power cord for ten seconds or more.
Check your firewall settings
If you have a firewall on your router or computer, see if it's blocking communication between Remote and iTunes or your Apple TV. The Remote app uses TCP port 3689 and UDP port 5353 to communicate with iTunes and Apple TV.
On your Mac, make sure that the firewall isn’t set to "Allow only essential services." You don't need to edit the port addresses.
On Windows, allow iTunes to communicate through the firewall.
If you use other firewall software or hardware, check its user guide for how to open TCP port 3689 and UDP port 5353.
