this old problem, no 1 has yet answered it.

we see users have problems connecting mongolab using mongoose driver. root cause incorrect configuration of driver, particularly around timeouts. following connection example using mongolab-recommended driver options:

// mongoose 4.3.x var mongoose = require('mongoose');    /*   * mongoose default sets auto_reconnect option true.  * recommend setting socket options @ both server , replica set level.  * recommend 30 second connection timeout because allows   * plenty of time in 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 database connection establish, start app.                          });

if doesn't help, please ensure password or username doesn't has special character, try connect via cmd first.

hope helped :)
