title: Jenkins can't reach Sonarqube
body: <p>I am currently trying to get my Jenkins/Sonar integration to work.</p>
  
  <p>Here is what I have:
  Jenkins is working
  Sonarqube is working (reachable from webinterface)
  Ports are open</p>
  
  <p>However!
  I tried all possible settings, Jenkins insists that Sonarqube is Localhost:9000, no matter what I tell it (and even if, this should work too). This leads to following:</p>
  
  <p><a href="https://i.stack.imgur.com/uCBNV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uCBNV.png" alt="enter image description here"></a></p>
  
  <p>and ultimately lets the build fail.
  What could I try to rectify this?</p>
