title: Failed to connect to repository : Error performing command: git ls-remote -h git@gitlab.com
body: <p>I cannot get my Private project to link to Jenkins.</p>
  
  <p>All I get is:</p>
  
  <blockquote>
    <p>Failed to connect to repository : Error performing command: git
    ls-remote -h git@gitlab.com:MineJam/DiscordSync.git HEAD</p>
  </blockquote>
  
  <p>whenever I try to put the link to the repository in. Any suggestions?</p>
  
  <p>I've tried to look this up and change the link to a HTTPS link that still throws the same error.</p>
