Kibana 3 can't connect to elasticsearch - elasticsearch

Question

I have tried to setup a kibana 3 with elasticsearch and logstash.
When i go to 127.0.0.1/kibana i get following error:
Error Could not contact Elasticsearch at http://127.0.0.1:9200. Please ensure that Elasticsearch is reachable from your system.
And when I check the console log i get the following:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://127.0.0.1:9200/_nodes. (Reason: CORS header 'Access-Control-Allow-Origin' missing).
When I go to the url http://127.0.0.1:9200 i get the following JSON text
{
"name" : "Meteor Man",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "2.1.1",
"build_hash" : "40e2c53a6b6c2972b3d13846e450e66f4375bd71",
"build_timestamp" : "2015-12-15T13:05:55Z",
"build_snapshot" : false,
"lucene_version" : "5.3.1"
},
"tagline" : "You Know, for Search"
}
and in http://127.0.0.1:9200/_nodes I get the following:

Answer 1

You simply need to enable CORS in your elasticsearch.yml configuration file and restart ES, that setting is disabled by default.
http.cors.enabled: true
However, I'm not certain that Kibana 3 will work with ES 2.1.1. You might need to upgrade your Kibana in order for this work. Try to change the above settings and see it it helps. If not, upgrade Kibana to the latest release.
