Mongodb 网络错误在第一次尝试时无法连接到数据库

Question

我正在尝试连接到 mongodb atlas，但是我把它拿回来了。

MongoNetworkError：首次连接时无法连接到服务器 [accounting-shard-00-01-6tg4q.mongodb.net:27017] [MongoNetworkError：连接超时]

mongoose
  .connect(
    "mongodb+srv://user:password@url.mongodb.net/accounting?retryWrites=true&w=majority",
    {
      useNewUrlParser: true
    }
  )
  .then(() => {
    console.log("Connected to Mongo database for testing");
    app.listen(8000);
  })
  .catch(error => {
    console.log(error);
  });

其余的错误如下

{ MongoNetworkError: failed to connect to server [accounting-shard-00-01-6tg4q.mongodb.net:27017] on first connect [MongoNetworkError: connection timed out]

我也遇到了一个错误，原来我的学校当时阻止了对 mongo 的网络请求，但是当我使用 vpn 时，它可以工作。
