Hi, I am running a Jenkins 2.422 on my Windows 10 pro. My scheduled builds were running ok few days ago, all of a sudden I found that my Jenkins service failing to auto start. Below is the error block found in jenkins.err.log
java.io.IOException: Failed to start Jetty

Looks like my old configuration got corrupted. Can anyone guide me how I can recover it on a new instance?

The easiest thing to try would be to replace jenkins.war with the same version downloaded from jenkins.io. Or you could try running java -jar jenkins.war on the command line (make sure to set the correct env variables for things like JENKINS_HOME) and see if there are additional errors that would make it easier to determine what is going wrong. Outside of that, if you want to move things over to a new instance, you can copy most of the contents of JENKINS_HOME over to the new instances JENKINS_HOME. If the zip file issue remains, it is probably a plugin that is corrupted.
