This error usually relates to communication problems between the VPN client and Windows services. Fixing it involves checking system services, permissions, and network settings. Let’s start with some quick checks before diving into detailed solutions.

Follow the steps in order, as they begin with the easiest fixes and progress to more advanced methods. This ensures you don’t miss simple solutions that can save time.

Quick Note: Prerequisites and Basic Checks

  • Ensure your VPN client is up to date. Outdated software can cause compatibility issues.
  • Restart your computer. Sometimes, a simple reboot clears temporary glitches.
  • Check your internet connection. A stable network is necessary for VPN operations.
  • Run the VPN client as Administrator. Right-click the app and select “Run as administrator” to avoid permission issues.

Step 1: Restart the Remote Access Connection Manager Service

The Remote Access Connection Manager (RASMAN) service helps manage VPN connections. If this service is stopped or malfunctioning, the VPN client cannot communicate properly.

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter to open the Services window.
  3. Scroll down and find Remote Access Connection Manager.
  4. Right-click it and select Restart. If the service is stopped, choose Start.
  5. Close the Services window and try reconnecting your VPN.

Why this helps: Restarting this service resets the VPN connection manager, which can clear errors related to interprocess communication.

Step 2: Check the Windows Firewall and Antivirus Settings

Sometimes, your firewall or antivirus software blocks communication between the VPN client and Windows services.

  1. Open Windows Security by searching it in the Start menu.
  2. Click on Firewall & network protection.
  3. Select your active network and then click Allow an app through firewall.
  4. Make sure your VPN client is checked for both Private and Public networks.
  5. If you use third-party antivirus or firewall software, open its settings and ensure the VPN client is allowed.

Why this matters: Blocking the VPN client can prevent it from creating the necessary communication channels with Windows.

Step 3: Reset Network Settings

Network misconfigurations can cause communication errors between your VPN client and system services. Resetting network settings can often fix these issues.

  1. Open Settings from the Start menu.
  2. Go to Network & internet > Status.
  3. Scroll down and click on Network reset.
  4. Click Reset now and confirm when prompted.
  5. Your PC will restart automatically.
  6. After restart, try connecting to your VPN again.

Note: This will remove all your saved Wi-Fi networks and VPN connections, so you will need to set them up again.

Step 4: Reinstall the VPN Client

If the above steps fail, the VPN client installation might be corrupted. Reinstalling can replace damaged files and restore proper functionality.

  1. Press Windows + I to open Settings.
  2. Go to Apps > Installed apps (or Apps & features).
  3. Find your VPN client in the list and click the three dots next to it.
  4. Select Uninstall and confirm.
  5. Download the latest version of your VPN client from the official website.
  6. Install the VPN client, then restart your computer.
  7. Try launching the VPN client and connect again.

Step 5: Run System File Checker (SFC) Scan

Corrupted or missing system files can cause communication errors. Running the System File Checker helps repair such files.

  1. Press Windows + S and type cmd.
  2. Right-click on Command Prompt and choose Run as administrator.
  3. In the Command Prompt window, type the following command and press Enter:
sfc /scannow

The scan will take some time. Once finished, it will automatically repair any detected problems.

After the scan completes, restart your computer and check if your VPN client works without the error.

Alternative Methods and Advanced Options

If the problem persists, consider the following:

  • Create a new user account: Sometimes user profile issues cause problems. Creating a fresh account can help isolate the issue.
  • Check VPN client logs: Some VPN clients provide logs that may offer clues about the error.
  • Disable IPv6: Certain VPNs have issues with IPv6. You can disable it by going to Network & internet > Change adapter options, right-clicking your active network, selecting Properties, and unchecking Internet Protocol Version 6 (TCP/IPv6).
  • Update Windows: Make sure your system is fully updated through Windows Update, as patches often fix underlying bugs.
