This issue affects individuals who rely on VPN connections for remote access to company resources.
This error can be frustrating, especially in situations where colleagues have successfully connected to the same network without issues. In this guide, we will walk you through the troubleshooting steps to resolve this problem and regain access to your VPN connection.
🛑 Root Causes of the Error
- The primary reason for Error 800 connecting to VPN on certain networks is a configuration issue with the Windows 10 operating system.

Specifically, the PPTP (Point-to-Point Tunneling Protocol) and MS-CHAP2 (Microsoft Challenge Handshake Authentication Protocol version 2) are commonly used protocols for VPN connections.
- An alternative reason for this error could be a problem with the VPN server or the network infrastructure on the office network. It is possible that there are issues with the VPN server's configuration, firewall settings, or network connectivity that are preventing your device from establishing a secure connection.
