Running on a real device? Make sure both your device and the computer running the Metro bundler are connected to the same Wi-Fi network.

Still having problems? Here are some debugging tips:

1. Clear the cache: Use the react-native start –reset-cache command to restart the Metro bundler and clear its cache.
2. Check debugger port: Verify that the debugger on your device is configured to connect to the same port (usually 8081) where the Metro bundler is running.
3. Start debugger first: Try launching the debugger before starting your React Native app.
4. Debugger installation: Double-check that you have the React Native debugger installed correctly.
