This could be due to network issues, insufficient resources, or a problem with the data being fetched. To resolve this, you can try the following: 1) Check your network connection and ensure it’s stable. 2) Verify that your Elasticsearch cluster has sufficient resources (CPU, memory, disk space). 3) Check the data being fetched for any inconsistencies or corruption. 4) Review your Elasticsearch logs for more detailed error information.
