I am trying to install Kibana on my windows machine, it keeps giving me error. I have also tried to delete all Kibana task - curl -XDELETE http://localhost:9200/.kibana*
But still getting this error. Below are the logs. Any guidance would be appreciated.

Welcome to our community! 
You don't really want to do that, it's not deleting Kibana tasks, it deletes all of the persistent data that Kibana builds. Things like dashboards.
Can you connect to Elasticsearch from the same host that Kibana is on?
