Aerospike Java client EOFException - vagrant

Question

I am trying to connect to a Aerospike single node I set up using Vagrant on MacOSX. My AMC is running on localhost:2200. I am unable to connect to it successfully.
import com.aerospike.client.AerospikeClient;
public class AerospikeDriver {
public static void main(String[] args) {
AerospikeClient client = new AerospikeClient("127.0.0.1", 2200);
client.close();
}
}
I am getting this error in the first line itself. I tried changing the port to 3000 as well. Same error. Sometimes, I get SocketException as well.
Exception in thread "main" com.aerospike.client.AerospikeException$Connection: Error Code -8: Failed to connect to host(s):

My maven dependency for aerospike client is this:
<dependency>
<groupId>com.aerospike</groupId>
<artifactId>aerospike-client</artifactId>
<version>4.1.11</version>
</dependency>
This is my aerospike conf:
# Aerospike database configuration file.
# This stanza must come first.

What am I doing wrong? Need some help here. I am very new to aerospike. I tried searching everywhere, but couldn't find anything.
UPDATE
I am now using IP address 172.28.128.4 (got it from ifconfig command) and port 3000 to connect to aerospike. I am now getting Socket Timeout Exception.

If you setup a single node on vagrant on Mac, and you running you are application in an ide on mac - say eclipse - locoalhost on vagrant is exposed to the mac as 172.28.128.3 typically. running ifconfig in your vagrant shell will confirm that. if your application is running inside vagrant itself, then 127.0.0.1 should work, in each case, your application should specify port 3000. thats where aerospike server is listening. amc is a webserver that talks to aerospike on port 3000 and serves the dashboard on port 8081 by default. so its a monitoring and management gateway to aerospike via a web browser. also, in your aerospike config, suggest you use mesh config instead of multicast though for a single node it does not matter - you are not making a cluster. If you are new, if you download CE, you get complimentary access to Aerospike Intro course in Aerospike Academy. Take advantage of that - few hours investment. Otherwise here are some intro videos on youtube. ( 02-Intro to Aerospike and 03-handson )
