Hi,

I am having serious trouble upgrading my Jenkins Setup to Jenkins LTS JDK17 from JDK11.

My inbound agent can connect to the controller but every minute the connection is lost which kills all my running builds.

The biggest difference is that my older Jenkins Controller Version did support agents to connect without “-webSocket”, which doesn’t seem to work now anymore. Maybe this is the culprit?

Thanks for taking the time to read this.
