Hi! I understand your HanFit app won’t connect or load properly and keeps returning to the home screen (app icon). Let’s try to get this sorted out together.

First, to make sure I guide you correctly, could you tell me:
- Are you seeing any error messages before it returns to the home screen, or does it just flash back immediately?
- Have you tried any fixes already, like reinstalling the app or restarting your device?
- Also, is your Linux OS fully updated and stable? What version are you running if you know?

Meanwhile, here are some initial steps you can try on your Linux browser environment:

1. Clear App Cache and Data: Since you’re on Linux using WebKit, if this is a web app, try clearing your browser cache and cookies related to HanFit. Sometimes corrupted data can cause issues loading.

2. Check Network Connection: Ensure your internet connection is stable. Try loading other websites or services to confirm.

3. Update Your Browser: Make sure your WebKit browser and your OS packages are updated to their latest versions. Outdated components can cause compatibility issues.

4. Try a Different Browser: If possible, try loading the HanFit app in another browser to see if it behaves the same way.

5. Reinstall the App (if you use a native app): You can uninstall then reinstall the HanFit app completely to ensure you have the latest version and clear any corrupted installation files.

If none of this helps, we may need to look into app-specific logs or check for any server-side issues.

Could you please let me know which of these you’ve tried or if anything else stands out? That way I can assist you further.
