As a last resort, we'll also explain how to repair your iOS system if all else fails. By following the steps in this guide, you will be able to get your iPhone's VPN up and running again in no time.

Part 1: Why Is My VPN Not Working on My iPhone

If you’re wondering, “why is my VPN not working on my iPhone?” Here are a few possible reasons behind iOS 17 VPN not working.

  • The most common reason behind VPN not working is an unstable internet connection. So make sure you’re connected to a stable network.
  • It's also possible the VPN app itself is experiencing issues. Sometimes apps can have bugs or become unstable through updates. This may disrupt the VPN connection. You may need to restart the app or, in severe cases, reinstall it.
  • Another reason could be server-related. VPN services operate through network servers around the world. If the server you've selected is offline or overloaded, you may lose your connection. Try switching to a different server location to see if that helps.
  • Lastly, iOS updates can also make your VPN not work properly. New updates sometimes come with bugs and glitches, interfering with your VPN connection.

Part 2: How to Enable VPN on iPhone in iOS 17/16

There are a couple of ways to enable VPN on your iPhone. The first one is to use the built-in VPN in your iPhone’s settings. Use this method only when you have manual configuration. Here are the steps you’ll need to follow.

  • Go to “Settings”. Tap “General.”
  • Scroll down and tap on “VPN & Device Management.”
  • Tap on “VPN”.

  • Enter the VPN configuration that you have to connect to this VPN connection.

In case you don’t have a manual configuration to connect to a VPN, there is another simple method you can try. The other common way to access a VPN is by downloading and installing the official app of your VPN provider. To do that:

  • Go to the App Store.
  • Type in “VPN” or the name of a particular VPN provider in the search bar. A list of VPN providers will come up that you can choose from.
  • Download the app, launch it, and sign up or log in with your account details. The app will guide you through any remaining configuration steps specific to that service. And you can easily enable and disable the VPN with a single tap directly from the app.
