Welcome!

Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.

Instead, paste the text and format it with `</>` icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

That said, if you are using a 8.x version, you should try https instead with the `--insecure` option.

If you are not, please share the full logs of Elasticsearch.

Your cluster is setup with TLS enabled. So you need to access it over https, not http. Try

```auto
curl -X GET https://localhost:9200

```

FWIW, there is no need to use `-k` or `--insecure` when accessing a self-configured 8.x cluster. The HTTP CA cert is available at a specific location, you can use `--cacert config/certs/http_ca.crt` with curl.
