com.mongodb.MongoTimeoutException: Timed out after 20000 ms while waiting for a

[navaneet...@gmail.com]

this is my java code:

MongoClientOptions mc = MongoClientOptions.builder().sslEnabled(false).sslInvalidHostNameAllowed(true).serverSelectionTimeout(20000).build();

MongoClient mongoClient = new MongoClient("mongodb://<username>:<password>@name-shard-00-01-nsbco.mongodb.net:27017,name-shard-00-00-nsbco.mongodb.net:27017,name-shard-00-02-nsbco.mongodb.net:27017/dbname?ssl=true&replicaSet=name-shard-0&authSource=admin",mc);

        MongoDatabase mydatabase = mongoClient.getDatabase("dbname");

im getting the following error:

com.mongodb.MongoTimeoutException: Timed out after 20000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}.

Hi

It looks like you’re trying to connect to MongoDB Atlas using the Java driver. Is this correct?

If yes, you might be able to follow the steps outlined in the Java driver example. Please ensure that you are using the latest Java driver

If you’re still having issues connecting to Atlas, you might want to click on the Support button on the sidebar to get Atlas-specific support.

Best regards
Kevin
