Remote DevTools loses connection to RN app

this old issue seems to be back https://github.com/zalmoxisus/redux-devtools-extension/issues/193

But to me it seems like an RN Debugger bug. It is in RN Debugger in the console log I see the error. I'm not using the Chrome extension.

seems to happen randomly in the RN Debugger console it says "[React DevTools] Connection to RN closed" same time app shows error below

React Native Debugger app version: 0.10.5
React Native version: 0.61.5
Platform: iOS
Is real device of platform: simulator
Operating System: macOS

```
Runtime is not ready for debugging. Make sure Packager server is running.
