Search - Request Entity Too Large

Kibana version:
Kibana 6.8.0

Elasticsearch version:
AWS ES/Kibana 6.8.0

Describe the bug:
SearchError: Request Entity Too Large

    at processQueue (
    at Scope.$digest (
    at Scope.$apply (
    at done (
    at completeRequest (
    at XMLHttpRequest.requestLoaded (

Steps to reproduce:

  1. deploy the ES Kibana 6.8.0 in AWS
  2. deploy the Apache v2.4.46 in AWS EKS (and configure Kibana specific vhost config and Ingress)
  3. Hit Kibana in browser (chrome)

Expected behavior:
Should load the Kibana home page

Errors in browser console (if relevant):
This error occurs in the browser when hit the Kibana URL.

Provide logs and/or server output (if relevant):
Can not take the logs as the container has been restarted.

Any additional context:
We have not set LimitRequestBody in our config. Apache is deployed in AWS EKS as deployment/pods and seeing this error when Kibana url is accessed.

Question is, do we have to Set the LimitRequestBody for/specific to each vhost config to fix this error. We can not reproduce this error. Would like to know if there is any specific apache config on Limits/Directive's we have to set for Kibana?

i am seeing other errors like below too.

please suggest.

If you are using Apache as a proxy in front of Elasticsearch for Kibana to connect through, the proxy needs to allow request payloads that are as large as the ones Kibana is sending. The proxy debug logs should help you find where the problem is.

Otherwise, if you are not using a proxy, you should look at the http.max_content_length in Elasticsearch: HTTP | Elasticsearch Guide [6.8] | Elastic
