Unknown error while connecting to ElasticSearch

[mastropi]

Hello,

I have downloaded the kibana-4.3.1-windows.zip file from the github page and copied its contents to the www directory of my WAMP server.

When I open the index.html file at the kibana4-static/public directory I get the following error message:

Note the following:

1. This is the same error message I get when the ElasticSearch server is not running (and of course in my case it is running, as verified by going to localhost:9200 and seeing the correct page)
2. The config file of kibana has the elasticsearch option pointing to the correct address:
   "elasticsearch": "http://localhost:9200/"
3. I am able to work with dynamic Kibana 4.3.1 (Build 9517) without any problems.

Thanks in advance for your assistance!

Hi Nagarajan,

No, I haven’t got any answers unfortunately…

I have ElasticSearch running only on localhost:9200.

When you say, “you are facing the same issue now”, do you mean that before you were able to work fine with Kibana static? If so, what changed in between?

Hi! Have you got any answer ?

I was finally able to solve this problem by performing the following steps:

Step 1: Solve the problem of "unknown error while connecting to ElasticSearch"

This problem can be solved by changing the ElasticSearch configuration file at config/elasticsearch.yml located in the ElasticSearch installation directory.
Edit the file and add the following two lines at the end:
http.cors.enabled: true
http.cors.allow-origin: "*"
Ref: https://gist.github.com/rmoff/379e6ce46eb128110f38

This makes sense as, if one uses the debugging tools in the web browser of choice to see what happens when launching Kibana4-static before doing the above changes, one sees the following warning message under the Console tab:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:9200/. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

Step 2: Solve the window size problem in Kibana

This problem can be solved by opening the public/index.js file in Kibana4's installation directory and replacing the line 87923 with the following line:
size: 10000
Ref: elastic/kibana#5904

UPDATE for Step 2: This issue is resolved with the newest version of Kibana4-static released in Mar-2016 with the latest patch that solves compatibility with ElasticSearch 2.x (Ref: #10).

HTH
