Why a VPN gets stuck connecting
If you are trying to figure out how to fix VPN stuck connecting, the problem usually comes down to network conflicts, app settings, server issues, or device-level restrictions.
The good news is that most cases can be resolved without advanced technical skills.
A VPN connection is a chain of checks between your device, the VPN client, the chosen protocol, the VPN server, and your local network.
When one part fails, the app may spin indefinitely on “connecting” instead of returning a clear error.
Start with the fastest fixes
Before changing advanced settings, test these basic steps first.
They solve many common connection hangs caused by temporary glitches, overloaded servers, or stale sessions.
- Disconnect and reconnect the VPN after waiting 30 to 60 seconds.
- Close the VPN app completely and reopen it.
- Restart your device.
- Switch to a different VPN server in the same country.
- Try a different Wi-Fi network or mobile hotspot.
If the VPN works on another network, the issue is likely with your current router, ISP, firewall, or DNS configuration rather than the VPN service itself.
Check whether the VPN service is having problems
Sometimes the issue is not on your device at all.
VPN providers occasionally experience server outages, maintenance windows, or regional routing problems that leave users stuck on the connection screen.
Look for these signs of a provider-side issue:
- The VPN fails on multiple devices at the same time.
- Several servers in the same region are unavailable.
- The provider’s status page or support channels report an outage.
- Other users mention the same problem in recent reports.
If server health is the cause, the best fix is usually to choose a different location or wait for the provider to restore service.
Change the VPN protocol
Protocol mismatch is one of the most common reasons a VPN remains stuck connecting.
Different protocols handle firewalls, NAT traversal, and network stability in different ways.
In most VPN apps, you can switch between options such as:
- OpenVPN
- WireGuard
- IKEv2/IPsec
- L2TP/IPsec
For speed and modern compatibility, WireGuard often works well.
For restrictive networks, OpenVPN over TCP can be more reliable.
If one protocol hangs, switching to another often gets the session through.
Turn off features that can block the handshake
Some privacy and security tools add extra steps before the VPN tunnel is established.
These features are useful, but they can also interfere with the initial connection.
Temporarily disable the following if your VPN is stuck connecting:
- Kill switch
- Split tunneling rules
- Threat protection or ad blocking features
- Multi-hop or double VPN
- Custom DNS settings inside the app
Once the VPN connects normally, re-enable these features one at a time to identify the one causing the delay.
How to fix VPN stuck connecting on Windows
On Windows, background networking services, security software, and adapter problems frequently interfere with VPN startup.
If your VPN stays on “connecting,” test these Windows-specific steps.
Update the VPN app and Windows
Outdated clients often break after system updates or protocol changes.
Install the latest version of the VPN app, then run Windows Update to patch networking components and drivers.
Reset the network stack
A corrupted Winsock catalog or IP stack can stop the tunnel from forming.
Open Command Prompt as administrator and run the following commands:
- netsh winsock reset
- netsh int ip reset
After running them, reboot the computer and try again.
Check firewall and antivirus software
Windows Defender Firewall, third-party antivirus tools, and endpoint security software can block VPN traffic.
Temporarily disable them for testing, or add the VPN app to the allowed list if your security policy permits it.
Reinstall the network adapter
In Device Manager, uninstall the virtual or physical network adapter used by the VPN if the app supports it, then restart the device so Windows rebuilds it cleanly.
How to fix VPN stuck connecting on macOS
macOS usually handles VPN connections well, but configuration profiles, keychain entries, and security permissions can still cause a hang during authentication.
- Quit the VPN app and reopen it from Applications.
- Remove and re-add the VPN profile in System Settings.
- Check that the VPN app has network and background permissions.
- Delete any old VPN configuration profiles that conflict with the current client.
- Restart the Mac after updating the app or macOS.
If the VPN uses a system extension or network filter, macOS may ask for approval in Security & Privacy settings.
Denied permissions can prevent the tunnel from finishing setup.
How to fix VPN stuck connecting on iPhone and Android
Mobile devices often fail to connect because of battery optimization, network switching, or restrictive app permissions.
If the VPN is stuck connecting on a phone, focus on app state and mobile network conditions first.
On iPhone
- Force close the VPN app and reopen it.
- Toggle Airplane Mode on and off.
- Check that the VPN app is allowed to use cellular data.
- Remove and reinstall the VPN profile if prompted.
- Update iOS and the VPN app.
On Android
- Clear the app cache and restart the app.
- Disable battery optimization for the VPN app.
- Check background data permissions.
- Clear saved VPN profiles if they are corrupted.
- Try switching from Wi-Fi to mobile data, or vice versa.
Mobile carriers and public Wi-Fi hotspots may also block VPN protocols, so testing on a second network is a useful diagnostic step.
Review DNS, time, and certificate settings
Authentication can fail silently when the device clock is wrong or DNS resolution is broken.
These issues are easy to miss because the VPN app may still appear to be working.
Verify the following:
- Your device date, time, and time zone are set automatically and correctly.
- DNS servers are not forcing a conflict with the VPN app.
- No custom certificate or enterprise profile is expired.
- The system has not blocked the VPN’s certificate authority or trust chain.
If the device time is off by several minutes, secure tunnels may fail certificate validation and remain stuck during the handshake.
Test for local network restrictions
School, workplace, hotel, and airport networks often block or throttle VPN traffic.
These networks may allow normal browsing but prevent encrypted tunneling from completing.
If you suspect local restrictions, try:
- Connecting through a mobile hotspot.
- Using OpenVPN over TCP on port 443, if your provider supports it.
- Switching to a nearby server with lower latency.
- Disabling captive portal limitations by fully signing into the network first.
If the VPN connects on a hotspot but not on the public or office network, the local firewall or router rules are the likely cause.
When to contact support
If you have already tried multiple servers, protocols, devices, and networks, the problem may be tied to your account or a deeper configuration issue.
Contact your VPN provider’s support team with detailed information so they can investigate faster.
Share the following:
- Your device model and operating system version
- The VPN app version
- The protocol you selected
- The server location you attempted
- Any error messages or screenshots
- Whether the issue happens on multiple networks
Support teams can often identify account-level limits, server-side routing problems, or known bugs affecting specific operating systems.
Prevent the problem from coming back
Once your VPN is working again, a few habits can reduce the chance of getting stuck connecting in the future.
Keep the app current, avoid outdated profiles, and test the connection after major OS updates.
- Update the VPN app regularly.
- Prefer modern protocols such as WireGuard when available.
- Keep security software configured to allow the VPN client.
- Use trusted DNS settings and accurate system time.
- Recheck VPN behavior after router, firmware, or OS changes.
Reliable VPN performance depends on clean software, compatible protocols, and a stable network path.
When one of those variables changes, connection stalls are often the first sign that something needs attention.
