Briefly, this error occurs when the HTTP channel through which Elasticsearch communicates with the client is closed before the response is fully sent. This could be due to network issues, client-side interruptions, or server-side problems. To resolve this, you can try the following: 1) Check the network connection between the client and the server. 2) Ensure the client is not closing the connection prematurely. 3) Investigate server logs for any issues that might cause the connection to close. 4) Increase the server’s timeout settings if the response is large and takes time to process.
