React Native: Axios Network Error from several domain

I'm new on React, and trying to get data from my server. But the result is 'Network Error'. I've try to change domain to https://randomuser.me/api/?results=5, and still error. But when I try to request to https://www.google.com or https://facebook.github.io/react-native/movies.json, the results is ok. I've opened site from my device browser, all site have no problem.

 axios.get(`https://randomuser.me/api/?results=5`)
                .then((result) => {
                    console.log(result.data);

            }).catch(error => {
                this.setState({error, loading: false, refreshing: false});
                console.log(error.message);
                console.log(error);

            });

Info:

• I'm using android emulator (NOX).

• Both of domain (my server & randomuser.me) use Cloudflare.
