Error while starting react native project

Question

I am just getting started in react native and followed all the steps given in https://reactnative.dev/docs/environment-setup for Windows -> Android .

And I have started the app using npm start after that I have tried to run the app in emulator with the command,

npm run android

and my package.json looks like,

 "scripts": {
 "android": "react-native run-android",
 "ios": "react-native run-ios",
 "start": "react-native start",
 "test": "jest",
 "lint": "eslint ."
 },

After entering the above command, I am getting the following error as connection refused,
