The VPN allows users to create a private network from a public internet connection. In this way, they can protect their online privacy and maintain the data security. However, the VPN error seems to be unavoidable; it can occur on every single device. This post provides some useful methods for fixing VPN error on Windows 10.

VPN Error on Your Device

First of all, you should get to know what VPN is. Actually, its full name is virtual private network, which is able to extend a private network for you across the public network. With the help of VPN, users can protect their data well and exchange data with other devices directly via the shared or public networks (if data get lost from PC, how to recover them?).

Yet, the VPN could fail due to some reasons abruptly.

  • Windows 10 VPN not working after update
  • Windows 10 VPN connecting forever

Do you know how to settle down the VPN error yourself? If not, you should read the following paragraphs carefully. MiniTool provides useful solutions to various computer & disk problems; please ask it for help when you can’t fix the problem yourself.

  • Check the login credentials and configuration settings.
