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

In additopm please look closely at the Advice that was given to you here:

> Somewhat confusingly tcp6 refers to the mixed IPv4 and IPv6 stack, as you can see from this line which has an IPv4 address: tcp6 0 0 10.0.0.12:9300 :::\* LISTEN 1040/java This line means it’s listening on all interfaces: tcp6 0 0 :::9200 :::\* LISTEN 1040/java Please read [these docs](https://www.elastic.co/docs/reference/elasticsearch/configuration-reference/networking-settings#modules-network-binding-publishing) carefully for further information, noting in particular: It is usually a mistake to use 0.0.0.0 as a publish addr…

Also Please try not not open multiple topics on the same question.
