Usage

When the 460 Client closed connection prematurely status code is generated, it means that the client has closed the connection with the load balancer before the idle timeout period elapsed. As such, the client will not receive the HTTP response and is only recorded in the logs.

Note

Search engines like Google will not index a URL with 460 response status, and consequently, URLs that have been indexed in the past but are now returning this HTTP status code will be removed from the search results.

Takeaway

The 460 Client closed connection prematurely status code is a client error that is not sent to the client. Rather, it is stored in the AWS Elastic Load Balancer logs and indicates that the client closed the connection prematurely.
