title: Why Youtrack is not closing an issue by commit message?
body: <p>I have installed Youtrack standalone to my PC. And added Gitlab project to it. I created an issue for testing with id #BDX-1 in Youtrack.</p>
  
  <p>When I pushed commit with message <strong>"Youtrack test commit #BDX-1 Fixed"</strong> Youtrack didn't closed an issue automatically. Then I just attached gitlab commit in the VCS Changes section manually. This also didn't worked.</p>
  
  <p>Then I installed Upsource too, and wanted to connect it to the Youtrack. This try was also failed. I tried to install an external Hub and connect both Upsource and Youtrack to it. Upsource failed with error HTTP 403 and Youtrack could not be migrated because of: </p>
  
  <blockquote>
    <p>Hub provides single sign-on and shared user management in JetBrains
    web-based products.YouTrack always uses Hub for authentication,
    authorization, and user management, even when installed alone.</p>
    
    <p>If Hub integration is disabled, the following features are not
    available: LDAP/OAuth/Google authentication, CAPTCHA, and the most
    part of user registration settings.</p>
    
    <p>The following deployment models are supported:</p>
    
    <p>— Preconfigured Hub instance embedded in YouTrack distribution that works right away after installation. You can use this page to
    adjust connection parameters, if necessary.
    — External Hub instance that may be used by YouTrack to share user data with other JetBrains applications. <strong>Current installation does not
    support external Hub integration.</strong></p>
  </blockquote>
  
  <p>The version of Youtrack I have installed seems doesn't support Hub Integration, but anyway Youtrack should close an issue when VCS commits added manually, right?</p>
  
  <p>How can this be fixed?</p>
