title: Webhooks showing error 404, Build trigger in Jenkins not working when Jenkins is closed
body: <p>am new to Jenkins and is searching for one answer. Iam trying to configure Jenkins with Gitlab and is facing issues when I add Webhooks or Jenkins CI Integration in Gitlab. Gitlab is not able to connect to Jenkins.
  Also when I close Jenkins, the build is not running at the scheduled intervals by build trigger. </p>
  
  <p>I tried adding the Jenkins CI Url and secret token obtained from Jenkins, but when I test the hook, it shows this <a href="https://i.stack.imgur.com/O6wTT.png" rel="nofollow noreferrer"> error 404</a></p>
  
  <p>Any help is appreciated.</p>
