Debugging React Native on Android breaks when using Proxyman

Description

When using Proxyman as a proxy for an Android device's traffic while running a React Native application in development mode, if React Native debugging is disabled, the app does not work. React will stop with the fatal error Failed to connect to debugger! Timeout while connecting to remote debugger.

When this occurs you can see the websocket traffic in Proxyman: localhost_10-20-2022-15-28-04.proxymanlog.zip

It appears that Proxyman is intercepting the websocket requests which I believe React Native uses for debugging. Something isn't quite working correctly though.

Steps to Reproduce

1. Setup Proxyman as a proxy for an Android emulated or physical device
2. Launch a React Native app in development mode npx react-native start
3. Ensure the Android device has 8081 forwarded to the local dev machine adb reverse tcp:8081 tcp:8081
4. Run the app on the Android emulated/physical device
5. Open the React Native dev menu adb shell input keyevent 82
6. Enable debugging

Current Behavior

Application restarts in debugging mode, but immediately fails with:
Failed to connect to debugger! Timeout while connecting to remote debugger.

Expected Behavior

Application restarts in debugging mode and works without any errors.

Environment

• App version: Proxyman 3.11.0 (31100)
• macOS version: macOS Monterey 12.6 (21G115)
• Android version: 12 (via Android emulator), 13 (via Pixel 4a)
• React Native version: 0.63.4

Additional notes

This does not affect iOS when using either the iOS simulator or a physical iOS device. In this case I've noticed that websocket traffic does not show up at all in Proxyman; perhaps this is why iOS doesn't have the same issue?
