How to Fix the Attempted VPN Tunnels Failed Error

Resolving the “Attempted VPN Tunnels Failed” error (Error Code: 800) involves a systematic approach to identify and fix the underlying issues. Follow the next steps guide to help you troubleshoot and restore your VPN connection.

Solution 1: Restart Your Computer

Solution 2. Check Your Internet Connection

Solution 3. Verify VPM Server Details

Double-check the VPN server name, address, and type to ensure they are correct. Mismatched or incorrect server details can prevent a successful connection.

Solution 4. Adjust Firewall Settings

Your firewall setting may be blocking the VPN traffic. Check your firewall settings and ensure that it is not preventing the VPN connection. To rule out any blockages, temporarily disable your firewall or antivirus software. After disabling, attempt to connect to the VPN again. If it works, you may need to adjust your security setting to allow VPN traffic on specific ports, such as TCP port 1723 for PPTP VPNs.
