Send AWS S3 Events in CloudWatch to my server using Lambda in Java

I am trying to send a S3 event log to my server outside AWS in case of object level API call is triggered in my bucket using Lambda (upload, download, etc) but when I run it it returns timeout without any error mentioned. I suspect maybe it is because it can't send it to my server using HttpClient but not entirely sure.

Here is my Lambda function:

import java.io.IOException;
import java.io.UnsupportedEncodingException;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import com.amazonaws.services.lambda.runtime.events.S3Event;
import com.amazonaws.services.s3.event.S3EventNotification;
import com.amazonaws.services.s3.event.S3EventNotification.S3EventNotificationRecord;

public class S3EventProcessor implements RequestHandler<S3Event, String> {

    public String handleRequest(S3Event s3event, Context context) {
        S3EventNotificationRecord record = s3event.getRecords().get(0);
        String event = record.toString();
        String url = "http://myexampleserver.com";



HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(url);
        StringEntity entity = null;
        try {
            entity = new StringEntity(event);
        } catch (UnsupportedEncodingException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        entity.setContentType("text/plain");
        post.setEntity(entity);
        context.getLogger().log("Setting up post request");

        HttpResponse response = null;
        try {
             response = client.execute(post);
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        context.getLogger().log(Integer.toString(response.getStatusLine().getStatusCode()));
        String a = "Event: " +  s3event.getRecords().get(0).getRequestParameters().getSourceIPAddress();
        return a;
    }

}

Is my Lambda function correct?

Here is my log and error messsage:
