All parts of the stack must be on the same version. If you want kibana to look at elasticsearch 6.6 you will need kibana 6.6. I hope that helps. ---

we open Elasticsearch(6.6.1) adding to it we have changed elaticsearch.yml(LocalHost:9200 - LocalHost:9400)) D:\elasticsearch-6.6.1\bin\>elasticsearch

So you're running two different version of the stack on the same machine? Can you share the config for elasticsearch and kibana for both of those environments? I suspect there may be a config problem. ---
