GDAX Sandbox修复连接

Question

未从GDAX Sandbox HTTP连接获得任何响应。正在尝试连接gdax沙箱以修复连接以下订单。

连接的URL = https://fix-public.sandbox.gdax.com

java.net.SocketException: Unexpected end of file from server
    at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:851)
    at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:678)
    at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:848)

    at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(HttpsURLConnectionImpl.java:338)
    at com.coinbase.exchange.api.HttpConnection.main(HttpConnection.java:43)

用于建立HTTP连接和升级以修复的示例代码：

try {
    String httpsURL = "https://fix-public.sandbox.gdax.com";
    URL url = new URL(httpsURL);
    //URLConnection conn = url.openConnection();
    HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
    conn.setRequestProperty("Connection", "Upgrade" );
    conn.setRequestProperty("Upgrade", "fix" );

    conn.connect();

    System.out.println(" Connected url = " + url.toString());
    System.out.println(" getResponseCode = " + conn.getResponseCode());
}

沙箱已于2017年初至2017年年中关闭。我在gdax-java库中记录了这一点。据我所知，没有任何通讯被发送给开发人员，但在他们的社区页面IIRC中提到了这一点。
