Hi @kray Welcome to the community.

This is a common error when Kibana cannot connect to elasticsearch.

You need to tell us how you installed / What documentation you followed.

You will need to share both

kibana.yml and elasticsearch.yml

Are Kibana and Elasticsearch on the same machine? If not, is this hostname accessible from the Kibana machine?

Did you confirm that your Elasticsearch is running and acessible from the Kibana machine using a curl request for example?
