Hello Dal,
Thank you for reaching out with your VPN connection issue. Here are some steps to help you resolve the problem with your Windows 11 Home edition:
Issue Description:
You are trying to set up a VPN on your Windows 11 Home edition but receive an error message: "The remote connection was not made because the attempted VPN tunnels failed. The VPN server might be unreachable, or if the connection is attempting to use an L2TP/IPsec tunnel, the security parameters for IPsec negotiation might not be configured properly."
1. Ensure Windows is Up to Date:
- Go to **Settings** > **Update & Security** > **Windows Update** and check for updates. Install any available updates.
2. Check VPN Server Details:
- Verify that you have entered the correct network address, username, and password for the VPN.
3. Configure L2TP/IPsec Setting:
- Press **Win + R**, type
services.msc
, and press Enter. - Ensure that the **IPsec Policy Agent** service is running. If not, right-click it and select **Start**.
4. Edit Registry for IPsec Parameters:
- Press **Win + R**, type
regedit
, and press Enter to open the Registry Editor. - Navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent
. - Right-click in the right pane, select **New** > **DWORD (32-bit) Value**, and name it
AssumeUDPEncapsulationContextOnSendRule
. - Double-click this entry and set the value to
2
. Click **OK** and restart your computer.
5. Allow VPN through Firewall:
- Go to **Control Panel** > **System and Security** > **Windows Defender Firewall** > **Allow an app or feature through Windows Defender Firewall**.
- Ensure that **VPN** is allowed through the firewall.
6. Check VPN Type and Encryption:
- Go to **Settings** > **Network & Internet** > **VPN**.
- Select your VPN connection, click **Advanced options**, and ensure the VPN type is set to **L2TP/IPsec with pre-shared key**. Verify the pre-shared key is correctly entered.
7. Install and Use PIA Application:
- Sometimes using the official VPN application from your VPN service can resolve issues. Download and install the Private Internet Access (PIA) application from their website and follow the setup instructions.
8. Check Event Logs for Errors:
- Open **Event Viewer** by pressing **Win + X** and selecting **Event Viewer**.
- Go to **Windows Logs** > **System** and look for any errors related to the VPN connection for more detailed troubleshooting.
If you need further assistance after trying these steps, please provide more details about your setup and any specific error messages you see.
