Removing node – How to solve this Elasticsearch error

Briefly, this error occurs when a node in the Elasticsearch cluster is removed or disconnected. This could be due to network issues, hardware failure, or the node being deliberately taken down for maintenance or updates. To resolve this issue, you can check the network connectivity, ensure the hardware is functioning properly, or if the node was taken down intentionally, ensure it is properly reconnected and synced with the cluster after maintenance. If the node was removed due to a failure, you may need to add a new node to the cluster.

                if (markedTribeName != null && markedTribeName.equals(tribeName)) {
                    if (tribeState.nodes().get(discoNode.getId()) == null) {
                        clusterStateChanged = true;
              "[{}] removing node [{}]"; tribeName; discoNode);
            // go over tribe nodes; and see if they need to be added
