1. Using EMA as gradle dependency

implementation group: 'com.refinitiv.ema', name: 'ema', version: '3.6.6.0'

Java 17, Windows 10

2. I used example from https://developers.refinitiv.com/en/api-catalog/refinitiv-real-time-opnsrc/rt-sdk-java/tutorials#ema-consumer-posting-data-to-contribution-channel
Stuck on Establish an encrypted connection to the server step. Keep getting error:

Error text Tunnel Channel Closed

Here is my EmaConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<EmaConfig>

Here is my source code:

public class ContributorTest {
    public static void main(String[] args) {

        try {
            System.setProperty("java.util.logging.config.file", "src/main/resources/logging.properties");

            System.out.println("Contributing to Refinitiv Contributions Channel");

            System.out.println("Starting encrypted connection...");
            // Create an OMM consumer
            OmmConsumer consumer = EmaFactory.createOmmConsumer(EmaFactory.createOmmConsumerConfig()); <------ error here 
.....
        } catch (Exception excp) {
            System.out.println(excp.getMessage());
        }
    }
}

I followed pre-requirements:
- copied the RDMFieldDictionary and enumtype.def from EMA /etc directory.
- added the Comodo certificate authority to the keystore (the default Certificate Authority Keystore location in the Java directory)

Here is output logs:
