Could not connect to development server.

Ensure the following:

Node server is running and available on the same network - run 'npm start' from react-native root

Node server URL is correctly set in AppDelegate

WiFi is enabled and connected to the same network as the Node Server

URL: http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false

Connection to http://localhost:8081/debugger-proxy?role=client timed out. Are you running node proxy? If you are running on the device, check if you have the right IP address in RCTWebSocketExecutor.m.
