I launch elastic 7.9 by nomad. I have 3 master nodes, 3 data, 1 kibana, 1 ingest and 1 coordinator.
I set ELASTIC_PASSWORD for coordinator & added xpack.security.enabled: true to every config of nodes. I want only have access to kibana by login/password and be able created user/roles.
After first time mu cluster working good, but some times I becam get error ONLY in date node logs
> : Transport SSL must be enabled if security is enabled on a [basic] license. Please set [xpack.security.transport.ssl.enabled] to [true] or disable security by setting [xpack.security.enabled] to [false] > ERROR: Elasticsearch did not exit normally - check the logs at /usr/share/elasticsearch/logs/admitad-cluster-demo.log > ERROR:  bootstrap checks failed
master and other nodes doesn't have same error.
I don't want to complicate my schem and added ssl. Maybe I can enable security feature for kibana without ssl?
