Hi @hoangkhac
As @TimV mentioned in your other post you can add the necessary options xpack.security.enabled: false in your kibana.yml and elasticsearch.yml yourself.
Regarding your main issue now, it looks like Kibana can't connect to Elasticsearch
log [01:27:54.589] [error][status][plugin:security@6.0.0] Status changed from uninitialized to red - Authentication Exception
Verify that the credentials you have set in kibana.yml are correct
> elasticsearch.username:
> elasticsearch.password:
You can verify the correctness of the credentials by attempting to authenticate to Elasticsearch yourself with those
curl -XGET http://localhost:9200 -u <user>
replacing with what you have in kibana.yml
