Hi! I see you're having trouble with server connection issues on the NHK WORLD-JAPAN app. Let's work together to get this sorted out. First, could you please tell me a bit more about what exactly happens when you try to use the app? For example:
- Does the app give any specific error message or just say it can't connect?
- Are you using Wi-Fi or mobile data?
- Have you noticed if this started happening suddenly or after an update?

Meanwhile, I'll suggest some initial steps tailored for your Android device using WebKit:

1. Check your internet connection: Make sure your Wi-Fi or mobile data is working properly by opening a website or different app.

2. Restart your device: Sometimes a simple restart can refresh network settings and app connections.

3. Clear app cache and data:
- Go to Settings > Apps > NHK WORLD-JAPAN > Storage.
- Tap on "Clear Cache" first, then "Clear Data" (note this will reset the app’s settings).

4. Update or reinstall the app:
- Check the Google Play Store to see if an update is available.
- If the app is up to date, try uninstalling and reinstalling it.

5. Disable VPN or proxy (if any): Sometimes these can interfere with server connections.

6. Check for system updates: Go to Settings > System > Software Update to ensure your Android OS 10 is up to date.

If these steps don’t resolve the issue, it might be related to a temporary server outage or app-side issue.

Could you try these and let me know what part of the process you get to or what messages you see? That way, we can look deeper if needed.

Are you satisfied with this starting approach?
