MongoNetworkError：连接ETIMEDOUT

Question

有时我们的团队通过以下代码连接localhost上的mongodb数据库：

const mongoose = require('mongoose');
const CONN = 'mongodb://name:password@www.wecard.io:27017/myproject'

const option = {
    socketTimeoutMS: 30000,
    keepAlive: true,
    reconnectTries: 30000
};

mongoose.connect(CONN, option).then(
  () => { console.log('It is good: ' + CONN); },
  (err) => {
    console.error('Error: ' + err);
    console.log(err);
  }
);

我们的一个队友遇到了这个错误：

MongoNetworkError: failed to connect to server [www.website.com:27017] on first connect [MongoNetworkError: connect ETIMEDOUT 46.101.98.56:27017]

与此同时，如果我们将它连接到云服务器上，到目前为止它一直都很好。所以任何人都知道如何解决它？感谢。
