微信支付HttpHostConnectException:443问题

Question

自从14号微信服务器升级后，我们后台就开始时不时的出现该错误，百度了也没有相关解决办法，我们之前是http请求，现在改成了https请求还是有这个错误
下面是https请求的代码

 KeyStore keyStore = KeyStore.getInstance("PKCS12");
        FileInputStream instream = new FileInputStream(new File(keyPath + 
                "apiclient_cert.p12"));//加载本地的证书进行https加密传输
        try {
            keyStore.load(instream, password.toCharArray());//设置证书密码
        } finally {
            instream.close();
        }

        // Trust own CA and all self-signed certs
        SSLContext sslcontext = SSLContexts.custom()
                .loadKeyMaterial(keyStore, password.toCharArray())
                .build();
        // Allow TLSv1 protocol only
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslcontext,
                new String[]{"TLSv1"},
                null,
                SSLConnectionSocketFactory.
                                BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);

        String result = null;

        HttpPost httpPost = new HttpPost(url);

        //得指明使用UTF-8编码，否则到API服务器XML的中文不能被成功识别
        StringEntity postEntity = new StringEntity(postDataXML, "UTF-8");
        httpPost.addHeader("Content-Type", "text/xml");
        httpPost.setEntity(postEntity);
        RequestConfig   requestConfig = RequestConfig.custom()
                .setConnectionRequestTimeout(socketTimeout)
                .setSocketTimeout(socketTimeout)
                .setConnectTimeout(connectTimeout).build();
        //设置请求器的配置
        httpPost.setConfig(requestConfig);

        LOGGER.info("executing request" + httpPost.getRequestLine());

        try {
            CloseableHttpClient httpClient =  HttpClients.custom()
                    .setSSLSocketFactory(sslsf).build();

            HttpResponse response = httpClient.execute(httpPost);

            HttpEntity entity = response.getEntity();

            result = EntityUtils.toString(entity, "UTF-8");

        } finally {
            httpPost.abort();
        }

        return result;

下面是错误
