Slave machine is running on openJDK, not Oracle java. so I used IcedTea to run .jnlp. I checked my Jenkins service is running.

openjdkverion: java-1.8.0-openjdk-1.8.0.91-3

Also someone guild me where I can see the Jenkins log. I am running Jenkins master as a Docker container.

1. For Windows, go to Services (Start → Run: services.msc), find Jenkins and Jenkins Agent, right click → Restart.

2. If it does not help (UI is not responding) open the Windows Task Manager → Processes, kill the java.exe process, and restart the service once again.

ps -ef | grep jenkins
sudo kill -9 <pid>
