React native TypeError: Network request failed with fetch()

I'm using React native for developing an android application. With this fetch request I'm getting the error TypeError: network request failed:

fetch('https://pixabay.com/api/?key=MY_KEY&q='+ this.props.jsondata.city.name +'&lang=en&image_type=photo&orientation=horizontal&category=travel&safesearch=true')        .then(response => {            console.dir(response);            if (!response.ok) {                throw Error(data.statusText);            }            return response.json();        })        .then(json => {            console.log(json.hits[0].largeImageURL)            this.setState(() => {                return {backImage: json.hits[0].largeImageURL};            });        })        .catch(err => {            console.log('Unable to search image! '+ err);        });

I've already searched online but this problem appears only with localhost addresses or http, that is not my case. The request is inside the componentDidMount() function. I've made a similar request (with the same structure) in an another place of the application but there is no error there. I'm using a real android device to testing the app with the react-native app compiled in android native code.
