Check that you set up Home Sharing
Before you can share content, you need to turn on Home Sharing in iTunes on your computer, and on each device that you want to share content with.
Wake your computer and open iTunes
Make sure that the computer you want to share or stream content from (the host computer) is on and awake, and that iTunes is open. If iTunes is already open, quit and reopen it.
If you're using a Mac with an Apple TV, you can turn on an option that will let your Apple TV wake your Mac for services like Home Sharing. On your Mac, go to System Preferences > Energy Saver and select Wake for Wi-Fi network access. Learn more about the Wake on Demand feature.
Check for software updates
Check your Apple ID
Make sure that you're signed in with the same Apple ID on all of the devices that you use with Home Sharing.
In iTunes on your computer, go to File > Home Sharing. To use a different Apple ID with Home Sharing, choose Turn Off Home Sharing, then set up Home Sharing again.
You can set up Home Sharing on up to five computers. If you already set up five computers and want to add another, you can deauthorize one or more of your computers in iTunes. Go to Account or Store and choose Deauthorize This Computer.
On your iPhone, iPad, or iPod touch, go to Settings > Video.
On your Apple TV, go to Settings > Computers.
Check your network connection
Make sure that all of the devices you use with Home Sharing are connected to the same home network.
- If you have multiple routers, make sure that all of your devices are connected to the same router.
- If you use a Virtual Private Network (VPN), make sure that all of your devices are on the same VPN, or disconnect all devices from the VPN.
- If you have a guest network, make sure that all of your devices are on the same guest network, or connect all devices to the primary network.
Restart and update your router
- Turn your router off and back on. Check the router's documentation for instructions.
- If you're using an AirPort or Time Capsule, check for firmware updates. If you're using a different router, contact the manufacturer for help.
While your router is off, you won't be able to use Internet services like Voice over IP (VoIP) for phone calls, and you might need to reset other routers that you have in sequence.
Check ports and firewall settings
Home Sharing uses TCP port 3689 and UDP port 5353 to communicate between computers and devices on your home network. These ports might be closed or blocked by a firewall.
To check your firewall settings on a Mac, go to System Preferences > Security & Privacy and select Firewall. If your firewall is set to block all incoming connections or allow only essential services, click Firewall Options and edit these settings. Get help with third-party security software if you're using a PC, or you have another firewall set up on your computer or router.
To test your ports, try streaming shared iTunes content from a different computer or to a different device. Also try connecting your devices to a different home network (if you have one), or contact your Internet service provider or router manufacturer for help. Learn more about TCP and UDP ports.
