Failed Verification Issue on iOS 15? Here’s the Fix!

Are you getting the Failed Verification Issue when trying to install iOS 15?

The recent iOS 15 update has made some strides for better user experience and iPhone users are in on the hype. While installing this update isn’t supposed to be a complex task, you may face some difficulties due to the Failed Verification issue.

Users have reported that when they tap the button that installs the update from the Settings, their iPhone displays a message saying “Unable to Verify Update”. It can mean that the device isn’t connected to the internet.

While there may be issues with your device or your Wi-Fi, the problem could also be with Apple’s servers. With the ever-increasing number of Apple users, there are many people trying to install updates and that often results in overloading of the company’s servers.

Worry not, though. Whatever is causing the Failed Verification Issue on iOS 15, this article has you covered. 

Let’s discuss the fixes!

1. Check the Wi-Fi Connection.

The iOS 15 update is a large file so it requires proper and reliable internet access to download all the data from the Apple server. That is why it is important to make sure you have uninterrupted internet connection before you attempt to install it.

If the error persists, you will need to check the internet on your iPhone. You can do that by going to Settings, then Wi-Fi and ensure that it’s connected properly. Also, double-check your router and try restarting it before attempting to update again. 

In case your iPhone can’t connect to your Wi-Fi but your other devices can, you may need to check its network settings.

2. Reset Network Settings.

If you have a stable internet connection and there are no issues with its connectivity, then you can try resetting your network settings to get rid of the issue. 

To do this, follow these steps:

  1. Go to Settings.
  2. Next, click General.
  3. Then, click the Reset button at the bottom of the screen.
  4. Finally, click on Reset Network Settings.

This will reset all the network settings back to default, which might fix the network issues that cause the failed verification issue preventing you from installing iOS 15. 

Make sure you remember your WiFi password and try to connect to your router again.

3. Ensure There’s Enough Storage Space.

As previously mentioned, the iOS 15 update is a large file. In particular, it is 3.2GB in size. That’s how much storage space you need so that the update can be downloaded on your iPhone.

To make extra space on your device, you can try:

Doing these few steps can help make space for the new iOS 15 update on your iPhone.

4. Restart Your iPhone.

Sometimes, simply restarting your device will do the trick and get the update working. 

Here is what you need to do:

  1. If you have an iPhone 8 or earlier, hold down the power button. If you have an iPhone X or later, hold down the volume or side button. Do this until the Slide to Power Off prompt appears. 
  2. Follow as instructed on the screen to turn off your device.
  3. After your iPhone is shut down, restart it by holding the power or side button.

You can try this twice if the first time doesn’t work. If that still doesn’t make the glitch go away, try the next fix.

5.  Redownload the Update.

One of the best and quickest ways to resolve the issue is to delete the update file and download it again. 

Here are the steps to doing that:

  1. First, go to Settings.
  2. Then, click on General.
  3. Now click on iPhone Storage. You should see the iOS 15 update under the list of apps.
  4. Click on the update, then select Delete Update.

5. Now, you can redownload the iOS 15 update by going back to General. From there, click on Software Update and download the latest update.

6. Turn Off Your VPN.

This is a pretty basic solution but it works like a charm. With the VPN on, your iPhone will not be able to establish a connection with the Apple servers. So, if you’re using a VPN when trying to install the update, turning it off can fix the issue.

7.  Update Using a PC.

If none of the above fixes work, you can also try using your PC to install the update. 

Here are the steps:

  1. First up, make sure your computer has an internet connection and then launch iTunes on it. 
  2. Next, connect your iPhone to your Mac or Windows PC with a USB cable.
  3. Once connected, look for an iPhone icon in the left sidebar below Devices.
  4. Then, click on the Summary tab and tap on Check for Update.

5. When the dialog box appears showing there is an update available, tap Next and then Agree.

The PC should then be able to identify the updated package and start downloading it on your iPhone right away.

8. Check the Apple Status.

It might also be that the Apple services are down at the time you wish to install the update. Check their status from the Apple Support System status page and if they are down, then wait it out. As soon as the service is back, go ahead and install the update.

There is also an option to chat with Apple Support about your problem, or perhaps schedule a call. Apple continuously tries to manage the capacity of its servers by investing in better infrastructure. But they are still trying to catch up with the growing customer base, which means that this error is more common than you think. 

The fixes presented should easily help you resolve the Failed Verification Issue on iOS 15 and allow you to continue enjoying your iOS device with the new update. If you have any questions, feel free to reach out to us in the comments section below.
