Fix iTunes Error 3194 When Updating or Restoring iPhone or iPad


Method 1: Check your hosts file

One of the reasons why iTunes shows this error is because it cannot communicate with Apple’s update servers. So you have to check your hosts file and ensure that there is no entry for “”. Here’s how you can do it on Mac or Windows.


  1. Quit iTunes.
  2. Open Terminal.
  3. Enter the following command and then press the Enter key
    sudo nano /private/etc/hosts
  4. You’ll be prompted to enter the password you use to sign into your Mac. Type in the password and press the Enter key.
  5. Terminal will now display the content of the hosts file.
  6. Navigate through the file using the arrow keys and look if there’s any entry for “”.
  7. If you find it, add a # symbol followed by a space before “” like below:
  8. Press Control-O to save the hosts file.
  9. Press the Enter key when asked for the filename and Control-X to exit the editor.
  10. Now restart your Mac.


  1. Press Windows + R keys to open the Run dialog box.
  2. Type %WinDir%\System32\Drivers\Etc in the text field and then press the OK button
  3. Double click on the Hosts file to open it.
  4. If you see any entries for “” then remove it.
  5. Save the hosts file by pressing the Ctrl + S keys.

Once you’ve followed the above steps, the error should be fixed. Go ahead and try restoring or updating your iPhone or iPad in iTunes and you shouldn’t get the 3194 iTunes error anymore.

Method 2: Make sure you have a proper working internet connection

If you don’t have a proper internet connection, iTunes will not be able to establish a connection with the update servers. Make sure that your internet is working properly and then try again.

Method 3: DFU mode

You may have to put your iPhone or iPad into DFU mode for the update or restore to work successfully. To do so, follow the steps below:

  1. Hold the Lock/Sleep and Home buttons together for 10 seconds.
  2. Release the Lock/Sleep button but keep holding the Home button continuously until iTunes shows the message “Your device is now in recovery mode”.
  3. Once your iPhone or iPad is in recovery mode, proceed with restoring or updating it in iTunes.

Method 4: Restore or Update using another computer

As a last resort, if none of the above solutions work, consider using another computer to restore or update your iPhone or iPad.

Method 5: Use Dr.Fone Toolkit
