Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
opensearch.x86_64 2.4.1-1 installed on RHEL 8.7

Describe the issue:
Opensearch installation has been done on a clean RHEL 8.7 machine through the opensearch ansible-playbook installation method.

After a few attempts the installation went fine.

Opensearch service is running

As a newby opensearch admin I’m trying to get opensearch running on 1 host in a single-node configuration.

Can anyone please advise on how to get the connection on port 9200 running?

Any help is appreciated

@wilco How many nodes are in the cluster?
Please share the logs and opensearch.yml.

I’am using the opensearch-playbook on a single node with a var:

cluster_type: single-node

I’m currently reïnstalling openseach, opensearch.yml will be uploaded when available again
