title: hooking gitlab with jenkins
body: <p>I'm trying to connect Gitlab CE 8.16 with Jenkins 2.46.1 using the GitLab hook plugin 1.4 to trigger builds when push or merge. </p>
  
  <p>So I checked "Build when a change is pushed to GitLab", copied the GitLab CI Service URL: <a href="http://server:port/project/my-project" rel="nofollow noreferrer">http://server:port/project/my-project</a> and the security token, to gitlab webhook, disabled ssl verification and when I clicked on <code>Test</code>, I got this error : </p>
  
  <pre><code>Hook execution failed: execution expired
  </code></pre>
  
  <p>What am I doing wrong, please? How can I make it work?</p>
