Cant create Index Pattern (Getting 404 Error)

Dear All,

I am having trouble creating index-pattern in Kibana version 6.8.3 running with ES 6.8.3 I am getting the error below.

Couldn't find any Elasticsearch data

I do have data in the index. From the logs I could see following 404 error while clicking on create index-pattern.

:{"statusCode":400,"responseTime":61,"contentLength":9},"message":"POST 
 csearch/elasticsearch/*/_search?ignore_unavailable=true 400 61ms - 9.0B"}

Please help.

Regards,
Desly

If you run "GET _cat/indices" in the Dev Tools Console of Kibana do you get any results there?
