Mongo timeout exception

I was looking for a watch and I can't figure out why this doesn't work, can you please give me guys? I am trying to implement mongodb in my project everything seems to be correct, but when I try to change / access it it gives me this "Mongo Timeout Exception".

    try {
        MongoCredential credential = MongoCredential.createCredential(USER, DATABASE, PASSWORD.toCharArray());
        MongoClient mongoClient = new MongoClient(new ServerAddress(HOST), Arrays.asList(credential));
        DB database = mongoClient.getDB(DATABASE);
        DBCollection collection = database.getCollection(COLLECTION);
        DBCursor cursor = collection.find();
        cursor.next();
        System.out.println("Success!");
    } catch(Exception ex) { ex.printStackTrace(); }
