Briefly, this error occurs when Elasticsearch takes too long to recover its state after a node restart or a cluster restart. This could be due to a large number of shards, slow disk I/O, or network latency. To resolve this issue, you can increase the timeout settings in the Elasticsearch configuration, reduce the number of shards, or improve the hardware resources such as disk I/O or network speed. Also, ensure that the cluster state is not too large by limiting the number of indices and shards in the cluster.
