Elastic Stack Kibana

Hi,

I am run EFK stack on Kubernetes for logging. For elasticseach we have 2 data, 1 master and 1 client node. Everything is working fine but i randomly get 502 bad gateway error.

From dashboard:

Discover: Bad Gateway

SearchError: Bad Gateway

Endpoint triggered that is giving error:
https://kibana.logging.stakater.com/elasticsearch/_msearch?rest_total_hits_as_int=true&ignore_throttled=true

I have updated my nginx configuration etc. but still unable to resolve this.

P.s. Let me know if more information is required from my side

Hey @ahmedwaleedmalik, do your Kibana logs contain additional information regarding the error? Also, if you capture a HAR of the request which is causing the 502, it'll help us diagnose further.
