Failed to create elasticsearch client

[Deviad (Davide Pugliese)]

Hello everyone,
I pasted all the files in here:

https://gist.github.com/Deviad/486513dc0ab5f82f6ea1ba06d3dc9d6b

I am running elasticsearch in a container and fscrawler throws:
19:06:59.272 [main] FATAL fr.pilato.elasticsearch.crawler.fs.cli.FsCrawlerCli - We can not start Elasticsearch Client. Exiting.
java.net.ConnectException: Connection refused

Thank you in advance for your help.

Is your elasticsearch node running?

Could you share elasticsearch logs?

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.
