Description
Hi,
Since we upgraded to Jenkins Core 2.222.4 (to include the fix JENKINS-61409) and remoting 4.2.1
We are facing much more stability issue on the websocket connection. It was not the case before with remoting 4.2 (The only issues we faced was the large payload).
We can observe now, disconnection on the middle of builds
Connection break after a simple git checkout.

If you have any idea about what is causing the issue.
PS : I didn't had time to test using latest jenkins version and remoting 4.3. I don't know if it will change anything
PS2: Totally aware that Websocket are still in beta
Thanks!

Ok thanks, we will try to reproduce the issue on a clean infra
We were able to compare the Websocket vs the TCP with the same network component (Traefik 2 on Kubernetes which support HTTP and TCP routes)
Without any activity (no job running)
1) The TCP connection is completely stable after many days

Sadly the JNLP4-connect doesn't support SNI, which prevent us to use a single port to connect our external agent
Cannot guess why JENKINS-61409 would have caused issues with Traefik. That fix changed the details of how Remoting commands are encoded in WS—from one command = one WS frame to a more complex chunked framing implementation shared with TCP agents—but nothing essential about how the connection is started, or the outbound WS ping every 30s, etc. If you manage to find the root cause here it would be great.
Maybe like JENKINS-64598?
Unfortunately Remoting disconnections are not generally diagnosable from logs alone, and there could be any number of root causes. It would be very helpful if there were a known way to reproduce the problem from scratch in a clean environment.
