I have installed elasticsearch cluster on a Linux server. Initially I installed Elasticsearch 7.x (but then changed the elasticsearch to 6.8). Elasticsearch is running fine.
I did the same with Kibana on a Windows Server. initially installed version 7.x then uninstalled it and installed Kibana 6.8
When I run Kibana I get this error:

istant.
