SonarQube server [http://localhost:8233] can not be reached

[Abd-ksr]

I have followed all the steps to install

1. npm install -g sonarqube-scanner
2. created sonar-project.js as follows
   My react project runs on http://localhost:8237

const sonarqubeScanner = require('sonarqube-scanner'); 
sonarqubeScanner(
  {
    serverUrl : 'http://localhost:8237',
    token : "",
    options: {
      'sonar.projectName': 'My App',
      'sonar.projectDescription': 'Description for "My App" project...',
      'sonar.sources': 'src'
    }
  },
  () => process.exit()
)

while running 'sonar-scanner' i am getting following error
