To resolve this, you can check the network connectivity, ensure the node is running, and verify the configuration settings. If the node is down, restart it. If the configuration is incorrect, correct it and restart Elasticsearch. If the network is the issue, fix the network problem and ensure that the node can communicate with the rest of the cluster.

 } else if (remoteNode.isMasterNode() == false) {
 listener.onFailure(new ConnectTransportException(remoteNode; "non-master-eligible node found"));
 } else {
 transportService.connectToNode(remoteNode; new ActionListener<>() {
