Javascript 错误：连接ETIMEDOUT-在Meteor服务器上获取与Google的距离时

我使用谷歌查找距离和持续时间之间的服务器端使用流星2点。它工作正常，但突然出现以下错误：

Error: connect ETIMEDOUT at Object.Future.wait (/root/.meteor/packages/meteor-tool/.1.1.10.ki0ccv++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/server-lib/node_modules/fibers/future.js:398:15)

以下是我在服务器上的代码：

 var url = 'https://maps.google.com/maps/api/directions/json?language=en&origin='+origin+'&destination='+destination+'&sensor=false&key='+this.directionsApiKey;

 var result = Meteor.http.get(url);

 if(result.statusCode == '200' && result.content){

    var content = JSON.parse(result.content);

    if(content && content.routes && content.routes[0] && content.routes[0].legs && content.routes[0].legs[0]){

        var tmp = content.routes[0].legs[0];

        if(tmp.distance && tmp.distance.value){

            distance = tmp.distance.value;
        }
        if(tmp.duration && tmp.duration.value){

            duration = tmp.duration.value;
        }
    }
}

我的http请求似乎超时了。。我把代码也放在了try-catch中，但它不是catch部分。这里有什么问题
