Question

我正在尝试使用猫鼬执行与mongodb的连接，但会引发错误。这是我的代码：

mongoose.connect("mongodb+srv://username:password@cluster0-bocic.mongodb.net/test?retryWrites=true", {useNewUrlParser: true})
    .then(()=>console.log("Database connected..."))
    .catch(err=>console.log(err));

这是错误：

[0] { MongoNetworkError: failed to connect to server [cluster0-shard-00-01-bocic
.mongodb.net:27017] on first connect [MongoNetworkError: connection 5 to cluster
0-shard-00-01-bocic.mongodb.net:27017 closed]

Answer 1

如果要启用任何主机连接访问权限，则可以将以下IP地址设置为图集配置中的白名单：

0.0.0.0

然后，即使您的IP地址突然更改，您仍然可以连接。

Answer 2

我必须解决相同的问题：在最近三天内，我的应用程序（node.js，express，mongoose，graphql）连接到mongoDB（在云中）时没有任何问题，但是今天我得到了：

错误：MongoNetworkError：首次连接时无法连接到服务器[cluster0-shard-00-00-cpkkj.mongodb.net:27017]的连接[MongoNetworkError：到cluster0-shard-00-00-cpkkj的连接5 .mongodb.net：27017已关闭]

我验证了PC的IP，就是这样：它已更改，并且与我添加到白名单中的IP不再相同，因此我添加了新IP，问题得以解决。

MongoDB Atlas连接错误“无法连接到服务器...”
