title: Hangfire shows two instances running on the same server v.1.5.3 - Leads to errors
body: <p>I have followed the documentation specified <a href="http://docs.hangfire.io/en/latest/deployment-to-production/making-aspnet-app-always-running.html" rel="noreferrer">here</a> to make the application always running and enable Service Auto-start. For configuration I used the documentation specified <a href="http://docs.hangfire.io/en/latest/configuration/using-dashboard.html" rel="noreferrer">here</a> and in this application I'm using Hangfire version 1.5.3. I have two other Hangfire applications running on the same server, one is using Hangfire v.1.4.1 and the other is using 1.4.5. Both of these work flawlessly. Every application runs under it's own application pool and there is no difference to the code. </p>
  
  <p>The application that does not work adds a GUID after the port number as you can see in the pictures below. This application some times does not auto start and I think it has to do with the two server instances.</p>
  
  <p>I know that Hangfire has modified something with ServerName because if you use "BackgroundJobServerOptions" and "ServerName" variable you get the obsolete message:</p>
  
  <blockquote>
    <p>"Server Id is auto-generated now, and this option does not make sense
    anymore. Will be removed in 2.0.0."</p>
  </blockquote>
  
  <p>Has anyone experienced this and managed to solve it? </p>
  
  <p>Note: I'm not using BackgroundJobServerOptions in any of the applications and I have tried to reboot the server. </p>

  <p>The two applications that work:</p>
