Briefly, this error occurs when OpenSearch has been waiting for a specified “recover_after_time” period to recover the cluster state but it hasn’t received enough node responses. This could be due to network issues, slow nodes, or nodes being down. To resolve this, you can increase the “recover_after_time” setting to allow more time for nodes to respond. Alternatively, check the health and connectivity of your nodes, and ensure they are running properly. If nodes are down, bring them back up. If the network is slow, consider optimizing your network configuration.
