      Description

      Hi R. Tyler Croy and Olivier Vernin

      I have seen a lot of windows agents close their JNLP connection other times they don't respond to pings. I have not noticed any issues with Linux agents.

      Perhaps switching to Kafka remoting will help solve those connection issues though that seems like a more significant infra project.

      I welcome other suggestions would be great to have these intermittent connection issues resolved.

          We have retired all win2012 agents and moved completely to win2019. Is this issue still occurring?

          I work with a network that is consistently bad and I see JNLP errors all the time, for both Windows and RHEL agents.

          This is specific to windows agents on ci.jenkins.io, not general Jenkins usage.

          Shouldn't websocket could be a solution here? https://www.jenkins.io/blog/2020/02/02/web-socket/
