我从我的 Node 应用程序连接到 MongoLab 时遇到问题。当我在本地时，一切正常，但是当我将它上传到我的主机（很棒的Clever Cloud，你应该检查一下）时，它没有连接。我复制我的代码和日志。

var mongo = require('mongodb');
var client = new mongo.Db('tweets', new mongo.Server('ds051077.mongolab.com', 51077, {auto_reconnect: true, 'poolSize': 10}));
client.open(function (error, db) {
    if(error) { console.log(error); }
    db.authenticate('***', '***', function(err, success) {
        if(err) {
            console.log("MongoDB failed");
            console.log(error);
            return;
        }

        console.log("MongoDB client opened");
    });
});

我不得不说我很难看到这个问题，因为它在本地运行良好。有人有想法吗？提前致谢。
