Elasticsearch server is down or unreachable

Elastic Stack Elasticsearch
1

Hello there,

I keep getting this message when i start Kibana. But if i go look on my
server i see that elasticsearch is running perfectly

root@server:~# service elasticsearch status

    • elasticsearch is running*

Connection FailedPossibility #1: Your elasticsearch server is down or
unreachableThis can be caused by a network outage, or a failure of the
Elasticsearch process. If you have recently run a query that required a
terms 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.Possibility #2: You are running Elasticsearch 1.4 or
higherElasticsearch 1.4 ships with a security setting that prevents Kibana
from connecting. You will need to set http.cors.allow-origin in your
elasticsearch.yml 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, http://mycompany.com:8080, not
http://mycompany.com:8080/kibana.Click back, or the home button, when you
have resolved the connection issue

Plz some help

Hi

I am also facing same issues. Read some where that elasticsearch in not
running but when I tried with the url : http://localhost:9200, it is
showing the below message

{
"status" : 200,
"name" : "Tzabaoth",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "1.4.0",
"build_hash" : "bc94bd81298f81c656893ab1ddddd30a99356066",
"build_timestamp" : "2014-11-05T14:26:12Z",
"build_snapshot" : false,
"lucene_version" : "4.10.2"
},
"tagline" : "You Know, for Search"
}

it means, elasticsearch is running. Added below two lines in elasticsearch.yml

http.cors.allow-origin: "/.*/"
http.cors.allow-credentials: true

After doing all this steps also, facing same issues.

Please suggest me the way to solve this.

Thanks in advance to all.

I got it to work by adding

http.cors.enabled: true

and leaving the allow-origin out and the allow-credentials out.
allow-origin seems to default to anything if it is not present. cors is
disabled by default.

Apologies for resurrecting an old thread, just wanted to highlight that
this worked for me.
I was fronting K3 with Apache, tried enabling all the options within
elasticsearch.yml, then also in Apache and finally, in desperation, with
ngnix but enabling just that one line as Drew says works.
