阿里云视觉智能开放平台的接口调用，求解答

我想用java本地文件上传，但是报错com.aliyun.tea.TeaException和 java.net.SocketTimeoutException: connect timed out

 Config config = new Config();
 config.accessKeyId="";
 config.accessKeySecret="";
 config.type="access_key";
 config.regionId="cn-shanghai";
 config.endpointType="internal";
 Client client = new Client(config);
 RuntimeOptions runtimeOptions = new RuntimeOptions();
 config.endpoint="ocr.cn-shanghai.aliyuncs.com";
 RecognizeIdentityCardAdvanceRequest req = new RecognizeIdentityCardAdvanceRequest();
 InputStream inputStream = new FileInputStream(new File("D:/back.jpg"));
 req.imageURLObject=inputStream;
 req.side="back";
 RecognizeIdentityCardResponse rep = client.recognizeIdentityCardAdvance(req, runtimeOptions);

使用的maven依赖是

        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.5.9</version>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>ocr20191230</artifactId>
