Please don't post unformatted logs as they're very hard to read.

Instead paste the text and format it with \</\> icon, and check the preview  
window to make sure it's properly formatted before posting it. This makes it  
more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

You have configured Elasticsearch to use TLS on the transport layer so you need to configure your transport client to connect to Elasticsearch over TLS : See the relevant part of [our documentation](https://www.elastic.co/guide/en/elastic-stack-overview/current/java-clients.html#transport-client)

Note that the transport client will be deprecated in 7.0.0 in favor of the [High Level Rest Client](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.5/java-rest-high.html) so you might want to star using that instead.

From your error message, it seems that your cluster has SSL enabled for transport, so the configuration above isn't going to work.
