The server is under heavy load at the moment. Lots of users building Be patient and try again might work. Are you having issues compiling or using your app with an emulator or Companion?
The problem could be your code. How would we know. You didn't share an image so no one can provide suggestions on how to fix the App asap. 
if it needs fixing.
If you're testing at home, you should also make sure your phone is connected to your home Wifi instead of using cellular data.
