I am experiencing an issue where my Jenkins agent goes offline with the error message: “This node is offline because the JVM version of the agent is incompatible with the controller one.” This issue started after updating some plugins.

This node is offline because the JVM version of the agent is incompatible with the controller one.

Details:
****Jenkins version: 2.426.3

  • Jenkins Controller Java Version: 17.0.14
  • Jenkins Agent Java Version: 17.0.9
    Steps Taken:
  1. Verified that both the controller and the agent are running Java 17.
  2. Set the JAVA_HOME environment variable on both the controller and the agent.
  3. Updated the remoting.jar file.

Additional Information:

  • The issue started after updating some plugins.

Any assistance or suggestions to resolve this issue would be greatly appreciated.

Do you have installed the plugin Versions Node Monitors and configured it with paranoid++ maybe?

I figured out the issue, and it was due to the plugin Versions Node Monitors. I adjusted the node monitor settings, which resolved the problem. Thank you for your response.
