    • Blocker
    • Resolution: Fixed
    • core, remoting
    • CentOS root node and 2 macOS agents connecting to it through JNLP4.

    Description

      Seeing something that sounds similar to https://issues.jenkins-ci.org/browse/JENKINS-48754.

      "After having installed Jenkins Version 2.99, none of my agents did connect to the server anymore. Even a restart of the java script on the slave did not help."

      Workaround: Update Remoting on the agent side to 3.15

      Agent is launched like so:

      java -jar agent.jar -jnlpUrl https://<Jenkins URL>/computer/<AgentName>/<>.jnlp -secret <Agent Secret>
