FIX: What to Do: Error 3194 on iPhone, iPad and iTunes - 2021

Usually, updating your iPhone or other iOS device to a new version of the operating system or restoring a backup is a pretty smooth process. Just follow a few steps and in a minute or three your device will be ready to use again. However, in some cases, you may encounter error 3194 in iTunes or on your devices. In this case, you will not be able to update or restore your iPhone or iPad. How to fix error 3194 isn't obvious, but this article provides step-by-step instructions.

What are the causes of error 3194?

Apple says error 3194 occurs when iTunes can't connect to Apple's software update servers that are used to restore or update iOS. Activation servers play a crucial role. If you can't get in touch with them, your iPhone won't be able to restore or update. This seems to happen most often when something is wrong with iOS on the device. Either the iOS was changed by jailbreaking or the version of the iOS has expired, is no longer supported or is no longer up-to-date.

Fix Error 3194: Update iTunes

When you see error 3194 in iTunes, the first step in resolving a problem is a simple step: update iTunes to the latest version. While this isn't the most likely reason and is unlikely to solve the problem, it's easy, quick, and worth a try. It is possible that something in an old version of iTunes is blocking the connection you need.

Fix Error 3194: Modify Your Hosts Files

If updating iTunes didn't work, try editing your hosts file. This is pretty complicated, so if you are not tech savvy, find someone to help you out.

Error 3194 occurs when Apple servers cannot be contacted. The hosts file on your computer depends on how your computer accesses the internet. It is possible that an incorrect configuration in the file is causing the problem and editing the file can fix the problem. Here's what you need to do:

  1. Quit iTunes.
  2. Open your hosts file.
    1. On a Mac, start the Terminal program and type the following sudo nano / private / etc / hosts and click on return.
    2. On Windows, navigate to system32 drivers etc and double click on the hosts file. For more information about how to edit the Hosts file on Windows, see How to Edit the HOSTS File in Windows.
  3. If you are asked for the password that you use when you log on to your computer, enter it.
  4. Find the host file entry for gs.apple.com.
    1. NOTE: If you don't see gs.apple.comif the hosts file is not the problem and you can skip to the next section.
  5. Add # and then a space at the very beginning of the gs.apple.com Line.
  6. Save the file (Ctrl + O on a Mac).
  7. Close the file or the terminal program.
  8. Restart your computer.
  9. Update or restore your iOS device again.

Fix Error 3194: Check the network connection and security software

Since error 3194 is often a network problem, you need to make sure that there is nothing in your network or in its configuration. To do this, try the following:

  • Make sure your internet connection is working. Obviously, if you are not online, you will not be able to reach Apple's servers.
  • Uninstall or disable security software like a firewall (make sure you get it back when you're done!). Firewalls and similar tools can block connections to certain servers.
  • Restart your computer and / or modem.
  • If you're using WiFi, try connecting your modem directly via ethernet to confirm WiFi isn't the problem.

Fix error 3194: try another computer

If there is no way to fix the problem, try restoring or updating your iOS device on a different computer than before. This can work, but even if it doesn't, the computer can be eliminated as a source of the problem. If you can do that, you will be much closer to identifying the cause of the failure.
