I'm unable to connect to splunk using java application.

spideyweb008 — Mon, 14 Jan 2019 09:01:59 GMT

I'm accessing splunk via a VPN. So if I'm trying to access splunk via browser, after logging in using username and password, I have to provide a VIP access code as well to complete the authentication process.
In java, I've tried to execute the below two codes and for each code the corresponding exception that I got is also shared below.

Starting of my java file :

public class SplunkTestService {

public void getConnectionAndTest() {

    HttpService.setSslSecurityProtocol( SSLSecurityProtocol.TLSv1_2 );

// HttpService.setSslSecurityProtocol( SSLSecurityProtocol.SSLv3 );

    ServiceArgs serviceArgs = new ServiceArgs();
            ..........................

Code :1 :

ServiceArgs serviceArgs = new ServiceArgs();
serviceArgs.setHost("https://127.0.0.1");
serviceArgs.setPort(8089);
Service service = Service.connect(serviceArgs);
service.login("USERNAME","PASSWORD");

Exception : 1:

Can you try actual IP or localhost instead like serviceArgs.setHost("https://<IP or localhost>") instead of 127.0.0.1?
