I have set up elasticsearch cluster and try to use kibana, but it seems the kibana can not obtained the x-pack information ![curl-es](https://us1.discourse-cdn.com/elastic/original/3X/5/0/502188532e98960eac97e106c2e40091a491e6b3.png) ![kibana-error](https://us1.discourse-cdn.com/elastic/original/3X/8/2/82a26440d02b1e606732f38e1dda351b3e6d4cb6.png) here is my kibana and es config ``` server.host: "10.18.1.50" server.name: "mdw_dev" elasticsearch.url: "http://10.18.1.54:9200" elasticsearch.username: "kibana" elasticsearch.password: "MvHuH7yb2f9ZY1WgXFvh" logging.dest: /var/log/kibana/kibana.log ``` * * * ``` cluster.name: mdw_dev node.name: ${HOSTNAME} node.master: true node.data: true node.ingest: true path.data: /app/elasticsearch/data path.logs: /app/elasticsearch/log network.host: 10.18.1.54 discovery.zen.ping.unicast.hosts: ["10.18.1.53:9300", "10.18.1.54:9300"] discovery.zen.minimum_master_nodes: 1 xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.verification_mode: certificate xpack.security.transport.ssl.keystore.path: /app/elastic-certificates.p12 xpack.security.transport.ssl.truststore.path: /app/elastic-certificates.p12 action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*,.ml*,spn-*,* ``` ---

Please don't post pictures of text, they are difficult to read and some people may not be even able to see them 🙂 What version are you on? What is the output of the `_xpack` API? (ie what license are you using) ---

That's not really cool at all. Not only is it against the terms of the license, you're abusing our good faith. ---
