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. 

What you might see

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:

iTunes Errors between 3000–3999. 

Get started

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: 
  • phobos.apple.com
  • deimos3.apple.com
  • albert.apple.com
  • gs.apple.com
  • itunes.apple.com
  • ax.itunes.apple.com        
  • Verisign servers:
  • evintl-ocsp.verisign.com
  • evsecure-ocsp.verisign.com

Find a more complete list of ports used by Apple products. You might also need to configure your security software to allow specific services to run. 

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.

Test connectivity

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. 

 

I hope this information helps ....

Hi Ben White,

I don't have this information, you may need to contact your ISP or Microsoft's support site for this:

iTunes for Windows can't access the Internet if proxy settings are incorrect - Apple Support

iTunes for Windows can't access the Internet if proxy settings are incorrect

An incorrectly configured proxy can interfere with iTunes accessing the iTunes Store. You should check your proxy settings to see if the settings are the source of your issue.

 

 

If you see a message in iTunes when you access the iTunes Store or another online resource, check if other Internet applications, such as your web browser and email client, can connect. If they can't connect, you should try general Internet troubleshooting.

If you're using a web browser other than Internet Explorer and it can connect to the Internet but iTunes can't, see if Internet Explorer can connect. iTunes uses the web proxy settings from Internet Explorer to access Internet content. If your network uses an HTTP proxy, make sure that the settings are correct or disable them.

To check your web proxy settings, follow these steps:

1. Open Internet Explorer
2. In Internet Explorer, choose Tools >  Internet Options.
   Note: If you don't see the Tools menu, press Alt-T.
3. In Internet Options, click the Connections tab.
4. Click the LAN Settings button.
5. In the Proxy server section of the Local Area Network (LAN) Settings window, make sure your proxy settings are correct. If they're not, correct them.
6. If your settings are correct, turn off the proxy. To do this, deselect Use a proxy server for your LAN.
7. Click OK in both the LAN Settings window and the Internet Options window.
8. In iTunes, try to access the iTunes Store or another online resource.

You should check your proxy settings with your local network administrator.
