I am developing an android application using mongoDB for data storage, currently I am using Mongolab sandbox for data storage. I'm going to move the database to an Amazon Ec2 instance , and I configured it through the MMS service.
I created a database user, and I can connect to the database using putty and perform CURD operations. Right now, I'm learning how to connect to the Equator Ec2 from MongoDB's JAVA driver.
I am using this code right now to connect to the database
MongoClientURI uri = new MongoClientURI("mongodb://" + myUserName + ":" + myPassword + "@" + DB + "/" + DB_NAME + "?authMechanism=MONGODB-CR"); MongoClient mongoClient = new MongoClient(uri); MongoDatabase blogDatabase = mongoClient.getDatabase(DB_NAME); MongoCollection<Document> usersCollection = blogDatabase.getCollection("users");
But I can not connect the database. It gives me an error

Note. I did not disclose the host and port values in the error.
Can someone help me figure out what to do even if all the credentials are correct. In most of the posts I found, they asked to create a REST API for the connection, but I think there is some other way to connect with the JAVA MongoDB driver itself. Else has another way to access the database.
