Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Seed node cluster name mismatch expected ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: cluster and node.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up to analyze Elasticsearch configuration and help resolve this error.

Log Context

Log “Seed node {} cluster name mismatch expected” classname is RemoteClusterConnection.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                             try {
                                ConnectionProfile connectionProfile = connectionManager.getConnectionProfile();
                                handshakeResponse = transportService.handshake(connection; connectionProfile.getHandshakeTimeout().millis();
                                    (c) -> remoteClusterName.get() == null ? true : c.equals(remoteClusterName.get()));
                            } catch (IllegalStateException ex) {
                                logger.warn(() -> new ParameterizedMessage("seed node {} cluster name mismatch expected " +
                                    "cluster name {}"; connection.getNode(); remoteClusterName.get()); ex);
                                throw ex;
                            }

                            final DiscoveryNode handshakeNode = maybeAddProxyAddress(proxyAddress; handshakeResponse.getDiscoveryNode());
