Unable to connect to MongoLab from java driver - mongodb

Question

I have Mongolab account , there is only one user in that account.
I can connect to the DB using MongoChef tool, however when I try and connect to that DB from within Eclipse using the java driver 3.2.0 , I continuously get an authentication failure. I get the following error.I am on Java 7 .
EDIT
Java Code used to connect to the MongoLab hosted MongoDB instance.
String mongoURL = new StringBuilder().append("mongodb://").append(mongoUserName).append(":").append(mongoPassword).append("#").append(mongoServer).append(":").append(mongoPort).append("/").append(dbName).toString();
System.out.println(" The Mongo URL is " +mongoURL);
MongoClientURI uri = new MongoClientURI(mongoURL);
MongoClient mongo = new MongoClient(uri);
Exception received when trying to connect.
com.mongodb.MongoTimeoutException: Timed out after 30000 ms while

Answer 1

try this code:
ServerAddress addr = new ServerAddress(mongoServer, mongoPort);
MongoCredential credential = MongoCredential.createMongoCredential(
mongoUserName, mongoPassword, dbName);
MongoClient mongoClient = new MongoClient(addr, Arrays.asList(credential), null);
