"엑스포 상태바 설치" 이후 연결되어 있다가 혼자 Metro 끊어 져요 

작성한 코드 및 에러 메세지

Cannot connect to Metro.

Try the following to fix the issue:

- Ensure that Metro is running and available on the 

same network

- Ensure that your device/emulator is connected to your machine and has USB debugging enabled - run 'adb devices' to see a list of connected devices     

- If you're on a physical 

device connected to the same machine, run 'adb reverse tcp:8081 tcp:8081' to forward requests from your 

device

- If your device is on the same Wi-Fi network, set 'Debug server host & port for device' in 'Dev settings' to your machine's IP address and the port of the 

local dev server - e.g. 10.0.1.1:8081

Tip 1) </> 아이콘을 눌러 코드박스를 만들어 보세요.

Tip 2) Ctrl+A(맥의 경우 Command+A) 단축키로 코드를 한 번에 선택할 수 있어요!
