There was my mistake I've solved this error.

@AddzMDev what was the issue Im running into the same issue?

[AddzMDev]

In my case I just put wrong configuration.
For production and development environment I've use different database then to switch to the production environment I need to switch both the URL of database and service key.

@dkoshkin, when you get a chance, can you post back with whether or not @AddzMDev configuration suggestion helped?

There are nothing special. To explain that with my code here

func firebaseAuth(keyPath, fbDbURL string) (fb *firego.Firebase, err error) {
  d, err := ioutil.ReadFile(keyPath)
  if err != nil {
    log.Println("Error : ", err.Error())
    os.Exit(0)
  }

  conf, err := google.JWTConfigFromJSON(d, "https://www.googleapis.com/auth/userinfo.email", "https://www.googleapis.com/auth/firebase.database")
  if err != nil {
    log.Println("Error : ", err.Error())
    os.Exit(0)
  }

  fb = firego.New(fbDbURL, conf.Client(oauth2.NoContext))
  firego.TimeoutDuration = time.Hour * 2
  
  if fb == nil {
    err = errors.New("fails to initialize firebase")
    log.Println("Error : ", err.Error())
  }
  return
}

func main() {  
  keyPath := "/path/to/your/production/key" // make sure this path is point to your production key path
  url := "https://your_product_project.firebaseio.com/" // make sure this url is your production database 

  if auth, e := firebaseAuth(keyPath, url); e != nil {
    os.Exit(0)
  } 
}

My former mistake was I had change kyePath variable in main function to production key but url variable still point to development database then Unauthorized request. error occur
