Appium拒绝连接-Saucelabs

Question

在酱料实验室上运行appium脚本时，一段时间后自动出现异常：-Appium连接被拒绝。

这是我的DesiredCapabilities：-

DesiredCapabilities caps=new DesiredCapabilities();
        caps.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
        caps.setCapability(MobileCapabilityType.DEVICE_NAME, "XXXXX");
        caps.setCapability("deviceOrientation","portrait");
        caps.setCapability("appiumVersion", "1.10.1");
        caps.setCapability("browserName", "");
        caps.setCapability("newCommandTimeout", 30000);

        caps.setCapability("app", "XXXXXXXXX.apk");
        caps.setCapability("appPackage", "XXXXXXXXXX");
        caps.setCapability("testobject_api_key", "D8C2XX3B1XXXXXXXXX");
        caps.setCapability("testobject_session_creation_timeout", "900000");
        caps.setCapability("testobject_app_id ", "2");
        caps.setCapability("testobject_suite_name", "Default Appium Suite");
        caps.setCapability("testobject_test_name", "Default Appium Test");
        caps.setCapability("appActivity", "in.test.XXXXX.appmodule.XXXXXXXX");

运行脚本后，appium抛出连接被拒绝。 有什么问题吗？ 在此先感谢！
