- iTunes won’t open
- You can’t connect to iTunes Store to buy or download content
- iPhone, iPad, or iPod touch won't back up, restore, update, sync, or activate with iTunes

First try these basic steps to see if they resolve the issue. If they don’t, continue to the next section.
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.
