Hi there! Thanks for reaching out. I understand you're getting a "failed to connect to server" message when trying to sign into the YPT app on your Android 10 WebKit device, even after uninstalling, restarting, and clearing the cache. Let's work together to get this fixed.

To start, can you tell me if your device is connected to the internet via Wi-Fi or mobile data? Also, have you tried switching between these to see if the connection issue persists? Sometimes network connectivity or restrictions can cause this error.

In the meantime, here’s a step-by-step approach that usually helps resolve this:

1. Check Internet Connection:
- Make sure your device is connected to a stable internet network. Try opening a web page in your browser to verify it’s working.

2. Disable VPN or Proxy (if any):
- VPNs or proxy services can sometimes block the app from reaching the server. Temporarily turn these off.

3. Verify App Permissions:
- Go to Settings > Apps > YPT > Permissions, and ensure it has permission to access the internet and storage.

4. Check Date and Time Settings:
- Incorrect date/time can interfere with secure connections. Set your device to automatic date and time under Settings.

5. Try Connecting via Different Network:
- Use a different Wi-Fi network or switch to mobile data to see if the issue is network-specific.

6. Clear App Data (different from cache):
- Go to Settings > Apps > YPT > Storage > Clear Data. This resets the app and may help if corrupted data is causing the issue.

7. Ensure App Is Updated:
- Check the Play Store for any updates to the YPT app.

If after these steps you still see the “failed to connect to server” message, there might be a server-side issue or a problem with app configurations.

Could you also let me know if other apps requiring internet work fine on your device? This helps isolate if it’s device-wide or specific to YPT.

Let me know how these steps go! I’m here to help you get this sorted out.
