React Native fetch TypeError: Network request failed

Question

I am creating my 1st rect native app. Running on OSX using OS11 Iphone 6 simulator. Getting below error in https fetch call. Using XCode 9.

ExceptionsManager.js:73 TypeError: Network request failed
    at XMLHttpRequest.xhr.onerror (fetch.js:441)
    at XMLHttpRequest.dispatchEvent (event-target.js:172)
    at XMLHttpRequest.setReadyState (XMLHttpRequest.js:548)
    at XMLHttpRequest.__didCompleteResponse (XMLHttpRequest.js:381)
    at XMLHttpRequest.js:487
    at RCTDeviceEventEmitter.emit (EventEmitter.js:181)

React component fetch code. (which is sample code from react-native official example)

   getMoviesFromApiAsync() {
        return fetch('https://facebook.github.io/react-native/movies.json')
            .then((response) => response.json())
            .then((responseJson) => {
                return responseJson.movies;
            })
            .catch((error) => {
                console.error(error);
            });
    }

Do i really need to update info.pllist to enable Allow Arbitrary Loads ? I tried enabling that too once but did not work.

Package.json { "name": "rnstarter", "version": "0.0.1", "private": true, "scripts": { "start": "node node_modules/react-native/local-cli/cli.js start", "test": "jest" }, "dependencies": { "react": "16.0.0-beta.5", "react-native": "^0.49.1" }, "devDependencies": { "babel-jest": "21.2.0", "babel-preset-react-native": "4.0.0", "jest": "21.2.1", "react-test-renderer": "16.0.0-beta.5" }, "jest": { "preset": "react-native" } }

Answer 1

After disconnecting from my employer's network it started working. Strange that i can hit facebook api using my browser even when i am connected to employer's network.
