您使用的是什麼版本的貓鼬的，什麼是MongoDB的版本也MLAB –

是你確定你已經爲mongo實驗室提供了正確的地址和認證密碼？ –

@RaviShankar是的。即使它曾經工作過。 – rahmanisback

我接觸MLAB爲。這是他們的支持人員的迴應：

我們經常建議從Heroku連接時連接超時30秒。你可以看到我們的建議的貓鼬的配置在這裏： https://gist.github.com/mongolab-org/9959376

下面是在GitHub的要點連接配置：

// 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:[email protected]: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.       
});
