Stuck on an issue?

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);
});
