Resolve issues between iTunes and security software
If you can’t open iTunes, download content, sync your device, or use Home Sharing, you might have an issue with security software. Security software created by companies other than Apple can prevent iTunes from connecting to Apple servers. Sometimes you might see a numeric error message when you sync, update, back up or restore your device.
What you might see
- iTunes won’t open
- You can’t connect to iTunes Store to buy or download content
- Your device or Apple TV won’t back up, restore, update, sync, or activate with iTunes
- Error messages 2, 4, 6, 9, 1000, 1611, 9006, 9807, or 9844
First try these basic steps to see if they resolve the issue. If they don’t, continue to the next section.
- Set the correct date, time, and time zone on your computer.
- Log in to an administrative user account.
- Get the latest version of iTunes.
- Update OS X or Windows, and update your security software.
Configure your software
After you update your security software, configure it to let iTunes communicate through the ports and servers listed here. Configuration steps vary by software, so contact the developer for specifics. Blocked ports are often related to numbered errors in the 3000 range.
- Ports: 80 and 443
- Apple servers:
- Verisign servers:
Remove your software and proxies
If your PC or router is using proxy settings, try connecting to the iTunes Store without using an Internet proxy. On a PC, you can use the built-in diagnostics in iTunes to test your connections and generate reports.
If the issue continues, disable or uninstall your security software temporarily, but first note any licenses and confirm you can reinstall the software.
- Restart your computer and try to connect with iTunes again.
- Check your hosts file to verify that it's not blocking iTunes from communicating with the update server.
When you’re done with these steps, re-install and re-enable your security software to keep your system safe. If uninstalling your security software resolved the issue, contact the developer to help you configure the software to work with iTunes.
If you’re still having issues using AirPlay, Home Sharing, iTunes, or Remote, test the connectivity between the computers or devices in your house. They need to be connected to the same network and subnet.
