Unable to connect with remote debugger

I'm using React.JS and when I do react-native run-android (with my device plugged in) I see a blank page. When I shake the device and select Debug JS Remotely from the option list I see the following screen.

FYI:

OS: Ubuntu 16.04
Node version is: v4.6.2
java version "1.8.0_111"
react": "15.4.1
react-native": "0.38.0

In my case the issue was that the emulator was making a request to:

http://10.0.2.2:8081/debugger-ui

instead of:

http://localhost:8081/debugger-ui and the request was failing.

To solve the issue: Before enabling remote debugging on your emulator, open http://localhost:8081/debugger-ui in chrome. Then enable remote debugging and go back to the chrome page where you should see your console logs.

Solved the issue following:

• Press Cmd + M on emulator screen
• Go to Dev settings > Debug server host & port for device
• Set localhost:8081
• Rerun the android app: react-native run-android

Debugger is connected now!

I solved it doing adb reverse tcp:8081 tcp:8081 and then reload on my phone.
