I was getting this error while trying to connect to a controller from my agent. My agent and controller were using same java version in the process.

Hello @ruthvik ,

The error message you’re seeing, “Failed to send back a reply to the request… channel is already closed,” surely indicates that the communication channel between the Jenkins agent and the controller has been prematurely closed.
This can happen for various reasons, and it’s often related to network issues, security settings, or misconfiguration.

Does your Jenkins instance work well despite this (hopefully transient) error?
