title: SonarQube : SonarQube server can not be reached
body: <p>I'm new to SonarQube. I would like to implement SonarQube with Jenkins on my software factory. Before I started I read a artikel on the internet how to implement SonarQube with Jenkins (book DevOps). </p>
  
  <p>See pictures below:
  1. First, I created on SonarQube a Token on pasted it into Jenkins --> Server authentication token

  <ol start="2">
  <li><p>Setup SonarQube Scanner
  <a href="https://i.stack.imgur.com/bZ23u.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bZ23u.png" alt="Jenkins &gt; Global Tool Configuration"></a></p></li>
  <li><p>Build configuration on Jenkins Job.

  </ol>
  
  <p>When I rebuild my project on Jenkins, I got the follow Error: SonarQube server [URL] can not be reached</p>
  
  <p><a href="https://i.stack.imgur.com/ezt8O.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ezt8O.png" alt="Error Message Build"></a></p>
  
  <p>When I clicked on the URL message, my browser will redirected me to SonarQube page</p>
  
  <p>Can anybody help me with my problem? </p>
  
  <p>Kind regards
