title: unable to connect to Sonarqube via intellij (SonarLint)
body: <p>I am trying to integrate sonarqube(version 5.1.2) with intellij(2016.2). I have added sonarLint plugin.
  when I am trying to add a sonar server to the sonarLint settings it asks for username and password for sonar server and other details like url.
  But it somehow is unable to connect to the sonar server and gives error :
