Awesome , glad it worked for ya, What I see was a mix up of ports and IP address.
Remember in this stack like @Wine_Merchant demonstrated. Port 9200 is for Elasticsearch/OpenSearch . Unlike ELK stack you would use port 9200. and last always double check your Config to make sure they match (i.e. ports, IP Addresses.
If you could make this as resolved for future searches that would be great
