title: Cloning from GitHub on Jenkins: could not load PEM client certificate
body: <p>I set up a build server and want to clone a project in Jenkins.</p>
  
  <p>I get the following error:</p>
  
  <blockquote>
    <p>fatal: unable to access '<a href="https://github.com/habitat-sh/sample-node-app/" rel="nofollow noreferrer">https://github.com/habitat-sh/sample-node-app/</a>': could not load PEM client certificate, LibreSSL error error:02FFF00D:system library:func(4095):Permission denied, (no key found, wrong pass phrase, or wrong file format?)</p>
  </blockquote>
  
  <p>It is on public GitHub, no certificates should be needed, everything is working correctly when I clone on terminal. Also, curl works without any problems.</p>
  
  <p>Do you have any ideas what causes the issue? Have tried a lot of stack overflow solutions, e.g. setting <code>git config --global http.sslVerify</code> to <code>false</code>, but none of them is working</p>
  
  <p>(the OS is macOS)</p>
