If you have recently run a query that required a <i>terms</i> facet to be executed it is possible the process has run out of memory and stopped. Be sure to check your Elasticsearch logs for any sign of memory pressure.<h5>Possibility #2: You are running Elasticsearch 1.4 or higher</h5>Elasticsearch 1.4 ships with a security setting that prevents Kibana from connecting. You will need to set the following in your elasticsearch.yml:<p><ol><li><i>http.cors.enabled: true</i></li><li><i>http.cors.allow-origin</i> to the correct protocol, hostname, and port (if not 80) that your access Kibana from. Note that if you are running Kibana in a sub-url, you should exclude the sub-url path and only include the protocol, hostname and port. For example, <i>http://mycompany.com:8080</i>, not <i>http://mycompany.com:8080/kibana</i>.</li></ol></p><h5>Click back, or the home button, when you have resolved the connection issue</h5></div></div></div></div></p>
