proxy checked, invalid

check-proxy is not working on my device i tested multiple valid proxies(http(s)/socks) but it always prints: proxy checked, invalid

//client.js
const checkProxy = require('check-proxy').check;
checkProxy({
    testHost: 'ping.rhcloud.com', // put your ping server url here
    proxyIP: '127.0.0.1', // proxy ip to test
    proxyPort: 44443, // proxy port to test
    localIP: '104.237.226.134', // local machine IP address to test
    connectTimeout: 15, // curl connect timeout, sec
    timeout: 10, // curl timeout, sec
    websites: [
        {
            name: 'example',
            url: 'http://www.example.com/',
            regex: /example/gim, // expected result - regex

        },
        {
            name: 'yandex',
            url: 'http://www.yandex.ru/',
            regex: /yandex/gim, // expected result - regex

        },
        {
            name: 'google',
            url: 'http://www.google.com/',
            regex: function(html) { // expected result - custom function
                return html && html.indexOf('google') != -1;
            },
        },
        {
            name: 'amazon',
            url: 'http://www.amazon.com/',
            regex: 'Amazon', // expected result - look for this string in the output
        },

    ]
}).then(function(res) {
    console.log('final result', res);
}, function(err) {
    console.log('proxy rejected', err);
});

Any server error is thrown as the proxy checked, invalid even if all the other things are running fine. Also if the proxy is not working, it gives the same error.

Exactly. Any error will throw proxy checked, invalid exception.
