Cannot access Elasticsearch outside

@Peter_Penzov Welcome to the community.

I am not familiar with the specifics of OCI but often / on other CSPs you will need to do some work to map the external IP and / or adjust the FW Rules.

This is most likely an OCI / Neworking issue not an Elastic Issue.

I think if you put "OCI no route to host" into your favorite search engine you will get some results

example
