我有一个使用第三方代理提供商（luminati.io）的网络爬虫，它已经为多个网站工作，没有任何问题。然而，今天我为一个新站点构建了一个爬虫，并遇到了 javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake 尝试连接到主机终结点时。我正在运行jdk版本1.8.0151。以下是代理客户端的代码：

public class ProxyClient implements Client
{
    private static final String username = "my-luminati-username";
    private static final String password = "my-luminati-pw";
    private static final String theHostname = "zproxy.lum-superproxy.io";
    private static final int port = 22225;
    public String session_id = Integer.toString(new Random().nextInt(Integer.MAX_VALUE));
    private WebClient theWebClient;

    public ProxyClient(String country){
        String myLogin = username+(country!=null ? "-country-"+country : "")
                +"-session-" + session_id;
        CredentialsProvider myCredentialsProvider = new BasicCredentialsProvider();
        myCredentialsProvider.setCredentials(new AuthScope(new HttpHost(theHostname, port)),
                new UsernamePasswordCredentials(myLogin, password));

        theWebClient = new WebClient();
        theWebClient.getOptions().setCssEnabled(false);
        theWebClient.getOptions().setJavaScriptEnabled(false);
        theWebClient.getOptions().setProxyConfig(new ProxyConfig(theHostname, port));
        theWebClient.setCredentialsProvider(myCredentialsProvider);
    }

    public HtmlPage request(String aUrl) throws IOException
    {
        return theWebClient.getPage(aUrl);
    }

    public void close() throws IOException { theWebClient.close(); }
}

下面是我正在运行的爬虫程序的简化版本，其中客户端作为proxyclient传入：

public class BusinessSearchTaxCrawler
{
    private String theBaseUrl = "https://apps.ilsos.gov/corporatellc/CorporateLlcController";
    private HtmlPage thePage;

    public BusinessSearchTaxCrawler()
    {
        thePage = null;
    }

    public boolean getBusinessMailingAddress(Client aClient, PropertyInfo aPropertyInfo)
    {
        try
        {
            thePage = aClient.request(theBaseUrl);   
        } catch (Exception aE)
        {
            aE.printStackTrace();
        }
        return false;
    }

}

这是错误的完整堆栈跟踪：

以下是我调试问题所采取的步骤：
-在没有代理的情况下运行代码可以正常运行。我可以使用以下代码连接到主机终结点而不会出现问题：

WebClient theWebClient = new WebClient();
            theWebClient.getOptions().setCssEnabled(false);
            theWebClient.getOptions().setJavaScriptEnabled(false);
            thePage = theWebClient.getPage(theBaseUrl);

-我试着添加 -Dhttps.protocols=TLSv1.1,TLSv1.2 到vm选项。这并没有改变结果
-我用它运行了应用程序 -Djavax.net.debug=all 并在堆栈跟踪中观察到以下情况：

我跑了 openssl s_client -connect ilsos.gov:443 并观察到：

SSL-Session:

    Session-ID: 66D1C471C9CA0DA2BCE6DA7675DF099D134BB0495C69D05B52AE0A5F4CF7976F

    Start Time: 1608833542
    Timeout   : 7200 (sec)
    Verify return code: 0 (ok)

最后，我读了一些补充的东西 System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2"); 我在 ProxyClient 班级。这也没有解决问题。
我还是一个新手，所以我不知道如何清楚地解释上面的调试信息。但我怀疑代理使用的是比我的机器更旧的tls协议。谢谢你的帮助。
