Let's fix your problem. Please follow these steps:

Open the app in the emulator
Press Ctrl + M to open the Dev menu, then tap Dev Settings
Choose Debug server host & port for device
Modify value to 127.0.0.1:8081 or simply localhost:8081 and now reload the app. You will now be able to debug.

PS: Some tutorial might have recommended you to install the Chrome extension to allow CORS, but it is not needed. The method above is simpler.
