Proxy does not work in nodejs request module

Question

var request = require('request');
    var proxyUrl = "http://" + 'EvjhdznB' + ":" + 'ouQEtyk7' + "@" + '5.188.222.111' + ":" + '8080';

var proxiedRequest = request.defaults({
      'proxy': proxyUrl
    });

    proxiedRequest.get("http://whoer.net", function (err, resp, body) {
      console.log(err)
      //console.log(resp)
    console.log(body)
    })

This proxy 'proxyUrl' work when connect to google.com but does not work for some other sites, for example whoer.net. it gives me this error

`502 Bad Gateway</h2><h3>Host Not Found or connection failed<`

also i have socks port 11319 for this proxy, and module request in nodejs gives another error

好的，我发现存在两种协议ipv6和ipv4，并且我的代理可以在ipv6上运行，没有多少网站支持新协议，并且它们仅在ipv4上运行
