Can't connect to free tier mongo cluster

Question

I am trying to connect to my Free Tier mongo cluster.
Through MongoDB Compass I get this error: Server record does not share hostname with parent URI.
It seems like a DNS issue, anyone else who has encountered the same issue?

Answer 1

UPDATE: It was a DNS issue. After changing to Google's DNS it seems to have resolved the issue.

Hi Michael Katsoulakis •,

Welcome to Microsoft Q&A forum.

As I understand, you could not connect to free tier mongo cluster of Azure Cosmos DB.

To check connectivity, follow these steps:

nc -v <accountName>.mongocluster.cosmos.azure.com 10260

If TCP connect to port 10260 fails, an environment firewall may be blocking the Azure Cosmos DB connection. Kindly raise support case if this fails.

OR

If your password includes special characters, and you are using your password in a connection string URI, encode the special characters.

Refer: https://www.mongodb.com/docs/atlas/troubleshoot-connection/#special-characters-in-connection-string-password

Let us know if this helps.

Thanks

Answer 4

i am strggling with the same error a bit of context .

mongo driver 7.0

mongoose ^8

consmosdb for mongo free tier

using the connection string provided in resource :

mongodb+srv://<userAdmin>:<password>@cluster3.mongocluster.cosmos.azure.com/?tls=true&authMechanism=SCRAM-SHA-256&retrywrites=false&maxIdleTimeMS=120000"

and the error is always

MongoAPIError: Server record does not share hostname with parent URI

if i run:

nc -v cluster3.mongocluster.cosmos.azure.com 10260
nc: getaddrinfo: nodename nor servname provided, or not known
MacBook-Pro-de-Francisco:~ franciscocodino$ 

but:

nc -v c.cluster3.mongocluster.cosmos.azure.com 10260
Connection to c.cluster3.mongocluster.cosmos.azure.com port 10260 [tcp/axis-wimp-port] succeeded!

dont understand were that extra c is coming from and how it reache to connect.

but either updating the connection string or removing +srv nor changing my local DNS resolver to google's (8.8.8.8) resolve the issue.

i removed local machine firewall, and allowed all IP ranges to connect to my DB adnd nothing.
