Run the app on a device or update your emulator play services and make sure you have internet connection.

Hi Akinyemi! Your logs shows that it's a network connection error which means that you should ensure that you have a good network connection before performing the request. FirebaseAuth is pretty fast. You may want to add a loader in your login UI so as to know when the request is performed. You could also use Android studio's debugger tool, just set a break point at the point of making the auth call. Also you could send a gist or code snippet of your authentication code if the error persists.
