Question about Connection Failed with ELK


I have a question. currently I am using ELK for my website log. everything
looks ok. however when I run the Kinba page from my chrome browser

about every 10 minutes or if I set auto refresh(any minutes) about 2 times
auto fresh. I will get following message

Connection Failed

Possibility #1: Your elasticsearch server is down or unreachable

This 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 higher

Elasticsearch 1.4 ships with a security setting that prevents Kibana from
connecting. You will need to set the following in your elasticsearch.yml:

  1. http.cors.enabled: true
  2. http.cors.allow-origin 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,,

Click back, or the home button, when you have resolved the connection

however I am sure connection is ok and if I just link to kinba page again
everything looks ok again.
Is any one experience this before?

Thanks in advance.
