cant connect to mongodb atlas

问题

Can't connect to mongodb atlas either via driver, mongoshell, or mongodb compass. Get to error: queryTxt ETIMEOUT

Error:  { Error: queryTxt ETIMEOUT clustermasjeed1-ekpfe.mongodb.net
    at QueryReqWrap.onresolve [as oncomplete] (dns.js:197:19)
  errno: 'ETIMEOUT',
  code: 'ETIMEOUT',
  syscall: 'queryTxt',
  hostname: 'clustermasjeed1-ekpfe.mongodb.net' }

I followed the guide from mongodb atlas (mongodb.cloud) on how to connect:

const MongoClient = require(‘mongodb’).MongoClient;
const uri = "mongodb+srv://<username>:<password>@clustermasjeed1-ekpfe.mongodb.net/test?retryWrites=true";
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
  const collection = client.db("test").collection("devices");
  // perform actions on the collection object
  client.close();
});

with username and password replaced with real string value. I have strong feeling the cause is +srv part. When using mlab before, the connection is only mongodb:// (without the +srv)

回答1:

Resolved the issue by contacting MongoDB support. The string URI should be changed to:

mongodb://<username>:<password>@clustermasjeed1-shard-00-00-ekpfe.mongodb.net:27017,clustermasjeed1-shard-00-01-ekpfe.mongodb.net:27017,clustermasjeed1-shard-00-02-ekpfe.mongodb.net:27017/test?ssl=true&replicaSet=ClusterMasjeed1-shard-0&authSource=admin&retryWrites=true

These are all the hostnames (primary and secondary) that you can see on the metrics tab of the cluster

I've faced a similar problem.

My string was:

.connect(
    "mongoURI": "mongodb+srv://user:<password>@cluster0-lo1zs.mongodb.net/<dbname>?retryWrites=true&w=majority"
  )

VS code terminal was shows this errors.

[0] Server started on port 9999<br/>
[0] queryTxt ETIMEOUT cluster0-lo1zs.mongodb.net<br/>
[1] Proxy error: Could not proxy request /api/profile/user/5f2be6e70fa40287805f6488 from localhost:3000

[0] [nodemon] app crashed - waiting for file changes before starting...<br/>

This raised an error I've solved by making this change:

.connect(
  "mongoURI": "mongodb://user:<password>@cluster0-shard-00-00-lo1zs.mongodb.net:27017,cluster0-shard-00-01-lo1zs.mongodb.net:27017,cluster0-shard-00-02-lo1zs.mongodb.net:27017/<dbname>?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true",
)
