Answer 1

I had the same case. Looking in the log

tail -f /var/log/elasticsearch/NODE.log

I saw this:

 [NODE_NAME] publish_address {10.XXX.XXX.XXX:9300}, bound_addresses {10.XXX.XXX.XXX:9300}
 [NODE_NAME] bound or publishing to a non-loopback address, enforcing bootstrap checks
 [NODE_NAME] node validation exception
 [1] bootstrap checks failed
 [1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
 [NODE_NAME] stopping ...
 [NODE_NAME] stopped

Solution:

Modify the archive /etc/elasticsearch/elasticsearch.yml in the line discorvery seed with this:

discovery.seed_hosts: ["127.0.0.1", "[::1]"]

Done.
