Hi,
We are in the process of setting up two Active-Active ELK Clusters across two independent Kubernetes clusters using (Elastic Cloud on Kubernetes) deployment.
Issue Identified - During the Remote Cluster configuration for CCR in the Local/Primary Cluster, we encountered the following error which is preventing the Local/Primary Cluster from establishing communication with the Remote Cluster.
"error.message":"Unable to open any connections to remote cluster [Test-Cluster]","error.stack_trace":"java.lang.IllegalStateException: Unable to open any connections to remote cluster [Test-Cluster]\n\tat org.elasticsearch.server@8.15.1/org.elasticsearch.transport.SniffConnectionStrategy$AbstractSniffResponseHandler.handleNodes(SniffConnectionStrategy.java:463)\n\tat org.elasticsearch.server@8.15.1/org.elasticsearch.transport.SniffConnectionStrategy$AbstractSniffResponseHandler$1.onFailure(SniffConnectionStrategy.java:446)
Both the ELK transport are exposed as NodePort on 32075 and direct telnet works as well.
Can someone please help here ?
Thanks
