VPN Stuck on Connecting in Windows 10: Fixes

If your VPN is stuck on “Connecting” in Windows 10, the quickest fix is usually to disable and re-enable the VPN adapter in Network Connections, or to restart the Windows IP Helper service. Below are the most effective troubleshooting steps, along with the background you need to understand why this happens and how to prevent it.

Why Windows 10 VPNs Get Stuck on Connecting

Windows 10 uses the built-in VPN client (based on the IKEv2, SSTP, L2TP/IPsec, or PPTP protocols) to connect to corporate or third-party VPN servers. When you click “Connect,” the operating system negotiates with the remote server through a series of steps: establishing a network tunnel, authenticating your credentials, and assigning an IP address. If any of these steps hang—due to network interference, incorrect settings, or a service failure—the status stays at “Connecting” indefinitely.

Common culprits include:

Windows IP Helper service (iphlpsvc) – handles IPv6 and tunnel traffic; a stopped or hung service blocks connections.
VPN adapter drivers – outdated or corrupted drivers can fail to initialize the tunnel.
Firewall or antivirus – third-party security software may block the VPN protocol ports (e.g., UDP 500, UDP 4500, TCP 443).
DNS settings – if the VPN server address doesn’t resolve, the connection stalls.
Incorrect VPN protocol or server address – a typo or mismatched protocol causes authentication to never complete.

Quick Fixes to Try First

Before diving into advanced settings, try these simple steps—they resolve a large percentage of stuck connections:

Restart the VPN connection – Disconnect (if possible), wait 10 seconds, and reconnect.
Restart your computer – Clears temporary network states.
Toggle Airplane mode – On laptops, turning Airplane mode on and off resets the Wi-Fi adapter.
Run the Windows Network Diagnostics – Right-click the network icon in the system tray and select “Troubleshoot problems.”
Check the server address – Ensure the VPN server hostname or IP is correct and reachable (ping it from Command Prompt).

If these don’t work, move on to the service and adapter fixes below.

Restart the IP Helper Service

The IP Helper service (iphlpsvc) is essential for VPN tunnels in Windows. A common fix is to restart it:

Press Win + R, type services.msc, and press Enter.
Scroll to IP Helper (or “IP Helper Service”).
Right-click it and select Restart. If it’s not running, right-click and choose Start.
Set its startup type to Automatic (right-click → Properties → Startup type).
Try connecting to your VPN again.

If the service fails to start, check the Windows Event Viewer (under Windows Logs → System) for errors related to iphlpsvc—often caused by a misconfigured IPv6 or a third-party network filter.

Reset the VPN Adapter

Sometimes the virtual VPN adapter gets stuck in a bad state. Resetting it forces Windows to reinitialize the driver:

Open Control Panel → Network and Sharing Center → Change adapter settings (or go to Settings → Network & Internet → Advanced network settings → More network adapter options).
Locate your VPN connection (usually named “VPN Connection” or the name you gave it).
Right-click it and select Disable.
Wait 5 seconds, then right-click again and select Enable.
Try connecting again.

If you don’t see the adapter, go to Device Manager → Network adapters and look for “WAN Miniport (IKEv2)” or similar. Right-click and choose “Uninstall device,” then restart your PC—Windows will reinstall the driver automatically.

Adjust VPN Protocol and Authentication Settings

Windows 10 supports several VPN protocols, and the wrong choice can cause a hang. In the VPN connection’s properties (right-click the adapter → Properties → Security tab), you can change:

Type of VPN – Try switching between Automatic, IKEv2, L2TP/IPsec, SSTP, or PPTP. IKEv2 is the most reliable for Windows 10, but some servers require L2TP or SSTP.
Data encryption – Set to “Require encryption” or “Optional encryption” depending on server policy.
Authentication – For L2TP, you may need to enable a pre-shared key (provided by your VPN provider).

Also, in the Networking tab, make sure only the necessary protocols are checked (usually just “Internet Protocol Version 4 (TCP/IPv4)”). Unchecking IPv6 can help in some cases.

Firewall and Third-Party Software Conflicts

Windows Firewall normally allows VPN traffic, but third-party firewalls or antivirus suites can block it. To test:

Temporarily disable your third-party firewall/antivirus (or its “web protection” feature).
Try connecting. If it works, add an exception for the VPN client or the VPN ports (UDP 500, UDP 4500, TCP 443).
Also check Windows Defender Firewall: go to Allow an app through Windows Firewall and ensure your VPN client (e.g., “Remote Access Connection Manager”) is allowed for both Private and Public networks.

If you’re using a third-party VPN app (like NordVPN or ExpressVPN), the issue may be in the app itself—try reinstalling it or using the built-in Windows VPN client with the same server details.

DNS and Network Reset Options

DNS resolution failures can cause a stuck connection. Try flushing DNS and resetting the network stack:

Open Command Prompt as Administrator.
Run ipconfig /flushdns and press Enter.
Run netsh winsock reset and press Enter.
Run netsh int ip reset and press Enter.
Restart your computer.

If that doesn’t help, perform a full network reset via Settings → Network & Internet → Status → Network reset. This removes and reinstalls all network adapters and sets many components back to default—you’ll need to reconnect to Wi-Fi and re-enter any VPN settings.

Frequently Asked Questions

Why does my VPN connect on other devices but not on Windows 10?

This usually points to a Windows-specific setting, such as the IP Helper service, a conflicting network driver, or a firewall rule that only applies to Windows. Try the service restart and adapter reset first, as those are the most common fixes.

Can a VPN be stuck on connecting because of a weak internet connection?

Yes, but a weak connection usually causes a timeout error rather than an endless “Connecting” state. If your internet is unstable, the VPN handshake may never complete. Test by browsing a website before connecting, or try connecting to a different server.

Should I use the Windows built-in VPN or a third-party app?

For corporate VPNs (often using IKEv2 or SSTP), the built-in client is fine. For consumer VPN services, the provider’s app often includes more features (like kill switch) and is easier to set up. If the app is stuck, try the built-in client with the same server details—it uses the same underlying protocols.

How do I know if the VPN server is down?

Check the provider’s status page (if they have one) or try connecting to a different server. You can also ping the server address from Command Prompt: ping yourvpnserver.com. If you get replies, the server is reachable; if not, the issue is network-side.

Will resetting Windows 10 fix VPN issues?

It can, but it’s a last resort. A full reset reinstalls Windows and removes all third-party software and drivers, which can clear persistent conflicts. However, you’ll lose installed apps and settings, so try all other fixes first.
