Elasticsearch doesn’t start: status=1/FAILURE (TLS/x-pack)

Elastic Stack Elasticsearch

I've seeing error and corrected it

[quote="manst, post:12, topic:123498"]
discovery.zen.ping.unicast.hosts: ["192.168.222.232:9300", "192.168.222.233:9300"]

Now my first node see the second.

And next bulb of errors:

[INFO ][o.e.d.z.ZenDiscovery     ] [master] failed to send join request to master [{data}{KC0RJjSzQhiagzzhHcDjag}{kC1Lw4_2RV6H8ebfXMgXGw}{192.168.222.233}{192.168.222.233:9300}{ml.machine_memory=1722236928, ml.max_open_jobs=20, ml.enabled=true}], reason [RemoteTransportException[[data][192.168.222.233:9300][internal:discovery/zen/join]]; nested: IllegalArgumentException[can't add node {master}{KC0RJjSzQhiagzzhHcDjag}{0lx-KxDlS5iVU-TI1xhMew}{192.168.222.232}{192.168.222.232:9300}{ml.machine_memory=2101534720, ml.max_open_jobs=20, ml.enabled=true}, found existing node {data}{KC0RJjSzQhiagzzhHcDjag}{kC1Lw4_2RV6H8ebfXMgXGw}{192.168.222.233}{192.168.222.233:9300}{ml.machine_memory=1722236928, ml.max_open_jobs=20, ml.enabled=true} with the same id but is a different node instance]; ]

solution for this error (you must deleted contents of data folder(/var/lib/elasticsearch/nodes/0) and restarted both the servers ):

Than I should change passwords , because i've had error:

/var/log/elasticsearch# curl -s 'localhost:9200/_cat/nodes?pretty'  -u elastic:pass
