java.net.SocketException : Connection reset for inputstream 异常

Question

我正在尝试从 https URL 下载文件。我可以使用以下代码从我的家用电脑下载文件。但是，我无法从公司机器上下载它。所需的 cacerts 已正确导入 java。我还可以从浏览器下载文件。我查看了其他线程的数量，但无法找到解决此问题的合适方法。这是我的Java代码

 try
  {
    url = new URL(url);
    HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
    if (httpURLConnection.getResponseCode() == HttpURLConnection.HTTP_OK)
            inputStream = httpURLConnection.getInputStream();
        else
            inputStream = httpURLConnection.getErrorStream();
 }
 catch (Exception ioe)
 {
    ioe.printStackTrace();
 }

这是我遇到的异常。我总是在 inputstream 处遇到异常。请记住，此代码在我的家用 PC 上 100% 有效。

对我来说很好:

    System.setProperty("http.proxyHost", "host");
    System.setProperty("http.proxyPort", "port");
    try {
        URL u = new URL("some url");
        HttpURLConnection huc = (HttpURLConnection) u.openConnection();
        InputStream is = null;
        if (huc.getResponseCode() == HttpURLConnection.HTTP_OK)
            is = huc.getInputStream();
        else
            is = huc.getErrorStream();
    } catch (Exception e) {
        e.printStackTrace();
    }
