An iTunes 3194 error usually occurs when trying to restore or upgrade your iPhone or iPad to another iOS. Before proceeding to fix this error, let’s take a look at the possible causes of this technical error and, based on this, perform the fixes to solve the problem.
Possible causes of the iTunes 3194 error when you restore or upgrade your iPhone / iPad
- Your iTunes cannot contact the Apple Software Update Server. This may be due to a locked connection, security software on your system, or a new entry in your hosts file.
- Apple will no longer sign the digital signature of the iOS version you are installing or updating.
- You have used a cracking software to modify your iPhone or iPad. Optimized hacking changes the hosts file and blocks Apple servers. This causes problems when you later try to upgrade your iOS to the latest version or restore from backup, causing the iTunes 3194 to fail.
Confirm your Internet connection
First, make sure that the computer running iTunes has an active Internet connection and has access to the outside world.
Sometimes, rebooting your computer and router/modem may solve connection problems.
Confirm that your connection is not blocked.
Then you want to make sure that routers, firewalls, security software, antivirus programs or similar software do not actively block domains and access to Apple servers.
An easy way to check this is to disable these types of filters and see if iTunes can recover your iPhone or iPad properly.

Restore or upgrade from another computer
Try to restore or update on another computer with a different Internet connection. This way, you can make sure that there are no problems on your computer that may prevent you from exchanging data with the update server.
Sometimes errors 1639, 3000-3020 and 3100-3999 (except 3194) are caused by your network settings. If your computer uses a managed network, please contact your network administrator. Proxy servers, firewalls and other network security measures can cause these errors. If necessary, find another network connection to restore the device. For example, if you are restoring at work, try restoring at home or on a friend’s computer and network.
Disable antivirus software
Check for antivirus software on your computer. Windows Protector, Avira, Norton, Kaspersky, etc. Close or deactivate the software and continue updating or restoring. Feel free to activate your antivirus as soon as you are done.
Check your hosts file
After you upgrade your Mac or iTunes to the latest version, check the hosts file to make sure your computer can contact the update server.
If you are using a Windows computer, follow the instructions on the Microsoft support website. Resetting the hosts file affects software services that rely on redirecting hosts files. If you are using Windows on your desktop computer, contact your IT department to make sure that applications will work properly after you reset the hosts file.
ITunes issues are mainly due to communication and connection problems with the Apple server. Troubleshooting can be easy. However, before upgrading or recovering, make sure that you have the latest version of iTunes installed on your computer.
