From all my research, the solution that worked for me is the following :

When you launch your app by typing react-native run-android, the error appears.

So, reach your directory containing "adb.exe" ( for me it was C:\Users\username\AppData\Local\Android\Sdk\platform-tools\ )

open a terminal from here. And type adb reverse tcp:8081 tcp:8081

Then, by reloading the app on the phone, it should work.

if you are using ReactNative in windows you must turn off the firewall then it will work!

That's how I resolved it.

Terminate your metro bundler > react-native link > react-native run-ios

It was not bundling because of some errors which are not showing into the emulator but just bundling was failed. After I re-bundled the package from starting, the error was resolved.
