I am trying to connect to my Elasticsearch server using the Java Api and shield. I can execute index, get, delete and search operations on the existing cluster using sense plugin (e.g) and via curl on 9200. I've seen other threads about this but none of them worked and none of them were trying to connect to a Elasticsearch webserver with shield.
I used the same API to connect with my localhost of elasticsearch and it worked fine however when I try to connect with my web server I always get the same error:
Error

Java code:
TransportClient client = TransportClient.builder()
.addPlugin(ShieldPlugin.class)
.settings(Settings.builder()
.put("cluster.name", ClusterName)
.put("shield.user", "USER:PASSWORD")
.build())
.build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(HOST), 9300));
I've tried as stated on Can't connect to ElasticSearch server using Java API to sync my Java API java version and my server and currently i'm using:
Java API:
C:\Program Files\Java\jdk1.8.0_92
Server:
"version": "1.8.0_91",
"vm_name": "OpenJDK 64-Bit Server VM",
I don't know if it has any problem using ...0_91 and 0_92 but doesn't seem to make any difference because the java API works weel on my localhost server.
If you need more information feel free to ask. Thanks in advance!
UPDATE:
Changes I did in elasticsearch.yml
shield.ssl.keystore.path: /usr/share/elasticsearch/bin/shield/elastic.jks
shield.ssl.keystore.password: password
shield.ssl.keystore.key_password: password
shield.transport.ssl: true
shield.http.ssl: true
shield.https.ssl: true
network.host: HOST_IP
network.publish_host: HOST_IP
shield.ssl.hostname_verification.resolve_name: false
Result of https://HOST:9200/_cluster/health?pretty=true

UPDATE2:
I've tried activate SSL according to official documentation and I got the following errors:
2082 [elasticsearch[Steel Serpent][transport_client_worker][T#1]{New I/O worker #1}] DEBUG org.elasticsearch.shield.transport.netty - [Steel Serpent] SSL/TLS handshake failed, closing channel: null

Temporary Solution
After that try I did as Vladislav Kysliy suggested and disabled SSL and it worked but I'm looking for a real solution and not a temporary one.
