Failled to connect to MongoDB Atlas cluster

[Renee Rojas]

Someone has successful connected to mongodb atlas cluster?

When i run it on a local instance v3.4.2 running on SSL it works fine, but when i try to connect to my atlas custer at same version it fails.

LOCAL URI
#mongodb.uri = "mongodb://localhost:27017/mr?sslEnabled=true&rm.tcpNoDelay=true&sslAllowsInvalidCert=true"
ATLAS URI
mongodb.uri = "mongodb://user:pa...@my-cluster-shard-00-00-ggnpd.mongodb.net:27017,my-cluster-shard-00-01-ggnpd.mongodb.net:27017,my-cluster-shard-00-02-ggnpd.mongodb.net:27017/test?authSource=admin&sslEnabled=true&sslAllowsInvalidCert=true"

Has some trick to use Atlas cluster?

i really don't know what is wrong, thanks.

There is no SSL/SNI support for now. You can create a feature request.

I had the same problem with MongoDB Atlas when the ssl=true was enclosed in the options.

Once I remove the ssl=true, the error changes to "server sandbox0-shard-00-01-xxxxx.mongodb.net:27017 sockets closed"

Any advice?

Hi Charlie Liu,

Acording to Lungang Fang from mongodb support, only atlas free requires SNI.

"Hi Renee,
 - For me the most strange that its connect locally using ssl in the same mongodb version.
The reason that it works locally but not on Atlas Free Tier is that local SSL does not require SNI to connect. In fact, Atlas M10 and above don't need SNI enabled either. Only Atlas Free requires SNI enabled."

[Renee Rojas]

Thanks Cédric, confirmed with mongodb support.

Hello i stumbled upon this during my search for answer  of connecting to Atlas Mongodb.

Is there a solution for this that you may know of ?

My mongo db atlas URI is  the following:

mongodb://USER:PASSWORD@
cluster.....-shard-00-00-d..j.mongodb.net:27017,
cluster.....-shard-00-01-d..j.mongodb.net:27017,
cluster.....-shard-00-02-d..j.mongodb.net:27017/DATABASENAME?
ssl=false&replicaSet=cluster.....-shard-0
&authSource=admin

Error i am getting is 

Unable to ensure uniqueness for usernames: MongoError: no valid replicaset members found

thank you.

ATLAS URI

mongodb.uri = "mongodb://user:pass@my-cluster-shard-00-00-ggnpd.mongodb.net:27017,my-cluster-shard-00-01-ggnpd.mongodb.net:27017,my-cluster-shard-00-02-ggnpd.mongodb.net:27017/test?authSource=admin&sslEnabled=true&sslAllowsInvalidCert=true"

As this message is coming from the Atlas RS, I suggest you first check with its support.

[Cédric Chantepie]

You can try 0.12.7-SNAPSHOT for the SNI support.

[Fernando Aspiazu]

Hi Cédric,

from which repository the version 0.12.7-SNAPSHOT is resolved?

Is there any workaround to connect with Atlas?

Thanks in advance
