Hi there! I see you mentioned that your NPV Tunnel app hasn't been working for the last two days. Let’s work together to get it back up and running.

Can you tell me a bit more about what's happening when you try to use the app? For example:
- Does the app open at all?
- Are you getting any error messages?
- Is it just not connecting, or does it crash?
- Have you tried restarting your device or reinstalling the app?

In the meantime, here are a few simple steps you can try on your Android 10 device with WebKit:

1. Restart your phone: This can sometimes clear temporary glitches.
2. Check your internet connection: Make sure your Wi-Fi or mobile data is working properly.
3. Clear the app cache:
- Go to Settings > Apps > NPV Tunnel
- Tap on Storage
- Tap "Clear Cache"
4. Update or reinstall the app: If there’s an important update or the app files got corrupted.
5. Check app permissions: Make sure the app has the necessary permissions to access the network.

If these don’t help, the problem might be related to your VPN configuration or server settings, especially if the app uses special protocols like V2Ray or SSH. If you want, I can guide you through checking or updating these settings.

Would you like me to walk you through these advanced steps or help find any updated configuration videos for NPV Tunnel? Let me know what you've tried so far!
