Hi @Brian-cf1 Welcome to the community!!
And.. 🙂
You're going to have to provide much more context if you want help...
What are you trying to do When you got this error, perhaps trying to get metricbeat to connect with elasticsearch? But hard
That's just a guess because no context...
If so, please provide your filebeat.yml and your elasticsearch.yml.
Did you set up Elastic search with the automatically configured security?
Did you run the following to test connectivity
`filebeat test output`
Did you try to run a curl command between the file beat host and the elasticsearch host using the URLs and credentials?
Provide the. .ymls and run these commands. Let us know what you find out. Perhaps we can then help.
