Hello,

Please do not share screenshots of error messages, they are pretty hard to read sometimes and some people may not be even able to read it.

Share the error log as plain text using the `</>` button in the editor.

Can you share your entire `elasticsearch.yml`?

Also, share the entire Elasticsearch error log, what you shared now is completely different from the error in your image.

The problem was fixed. the old elasticsearch.yml file wasnt getting updated. I am installing elastic stack with authentication using ansible playbook. The same isnt working for 8.5.1. Can you please share how to setup authentication for elk 8.5.1?
