这是一个非常古老的问题，但由于还没有人回答这个问题。

我们经常看到用户使用Mongoose驱动程序连接到MongoLab时遇到问题。根本原因几乎总是错误的驱动程序配置，特别是在超时周围。以下是使用MongoLab推荐的驱动程序选项的连接示例：

// mongoose 4.3.x
var mongoose = require('mongoose');



/* 
 * Mongoose by default sets the auto_reconnect option to true.
 * We recommend setting socket options at both the server and replica set level.
 * We recommend a 30 second connection timeout because it allows for 
 * plenty of time in most operating environments.
 */
var options = { server: { socketOptions: { keepAlive: 300000, connectTimeoutMS: 30000 } }, 
                replset: { socketOptions: { keepAlive: 300000, connectTimeoutMS : 30000 } } };       

var mongodbUri = 'mongodb://user:pass@host:port/db';

mongoose.connect(mongodbUri, options);
var conn = mongoose.connection;             

conn.on('error', console.error.bind(console, 'connection error:'));  

conn.once('open', function() {
  // Wait for the database connection to establish, then start the app.                         
});

如果这没有用，请确保您的密码或用户名没有任何特殊字符，请先尝试通过CMD连接。
