Possible Causes:

The VPN closing automatically can be caused by several factors. Here's a structured approach to diagnose and resolve the issue:

1. Browser Interference: The Close button might not work. Try holding Shift while clicking the Close button.
2. VPN App Settings: Check if the VPN app uses the default connection and disable that.
3. Default Internet Connection: The VPN might be using the default connection in your browser. Disable the app's default connection.
4. Browser Settings: Ensure the VPN service is private.
5. Plagiarized Plugins/Extensions: Check for any plugins that might interfere with the VPN.
6. Device Differences: Some issues might be specific to iOS or Android. Try other devices.
7. VPN Type: Ensure the VPN is private; using a public one might affect connection.

Troubleshooting Steps:

1. Turn Off Close Button: In the browser, disable the Close button to see if the VPN still connects.
2. Disable Default Connection: In the VPN app, disable the default connection.
3. Check Connection Source: Ensure the VPN is using a private service.
4. Explore Plugins: Look for plugins that might interfere with the VPN's settings.
5. Test on Different Browsers: Try using different browsers to see if the issue persists.
6. Device Compatibility: Check if the issue occurs on specific devices like tablets or phones.
7. Contact Provider: If issues persist, contact the VPN provider for assistance.

Conclusion:

By systematically addressing these areas, you can identify the root cause and resolve the VPN closure issue. If the problem persists, consider reaching out to the VPN provider or exploring alternative solutions.
