VPN Kill Switch: Guardians who keep your VPN connection safe

What is A Kill Switch on VPN? What to do If It Is Not Working? - MiniTool

Virtual Private Network (VPN) converts public Internet connections into secure and private networks. However, if your VPN connection is interrupted, your IP address is easily exposed to the tracker. How to ensure the security and anonymity of your internet connection? At this time, VPN Kill Switch can come in handy!

VPN Kill Switch, also known as a network lock, connection kill switch, or network kill switch, is a feature that automatically disconnects your device (such as a phone, tablet or computer) from the Internet when the VPN connection is interrupted. This way, your IP address and other private information will not be leaked.

When will VPN Kill Switch start?

Almost all networks will be interrupted from time to time. Once the VPN Kill Switch detects that your VPN connection fails, it will start automatically. The following situations may activate VPN Kill Switch:

  • Switch VPN server
  • Encountering unreliable network connections, such as public Wi-Fi
  • Wi-Fi signal strength is weak
  • Forgot to add exceptions to your VPN in your firewall
  • The VPN is not activated when the computer starts
  • Overuse causes excessive load

What to do if VPN Kill Switch doesn't work?

VPN Kill Switch may not work occasionally. The problem may be with the VPN service or on your device. If your VPN Kill Switch stops working, here are some tips:

Tips 1: Run VPN apps as administrator

The operation of the VPN Kill Switch may be blocked by your computer incorrectly, so you need to manually grant the VPN application permissions.

Step 1. Right-click the shortcut for the VPN application on your desktop and select Properties .

Step 2. Under the Compatibility tab, check Run this program as administrator and click OK to save changes.

Tips 2: Update and restart the application

Typically, most technical errors and failures are fixed in the latest version of the application. Therefore, you should update your VPN app in time and the VPN Kill Switch may work properly again after the update.

Tips 3: Modify firewall settings

Even if you can initially connect to a VPN server, your firewall may prevent VPN Kill Switch from re-establishing a VPN connection. If this is the case, you need to allow the VPN client to pass through the firewall. The operation method is as follows:

Step 1. Type Windows Defender Firewall in the search bar and press Enter .

Step 2. Click Allow Apps or Features via Windows Defender Firewall > Click Change Settings > Scroll down and click Allow Another App .

Step 3. Click Browse to select the application's executable file > Click the Network Type button > Check the two check boxes > Click OK > Click Add to save changes.
