title: Xamarin IOs simulator doesn't start after Visual Studio Update
body: <p>I have updated Visual Studio to 15.8.4. I code on a PC machine and have a MAC connected via SSH for builds and debuging via the simulator.</p>
  
  <p>Before the simulator would just start up on my MAC. Now a new window comes up on a PC called iOS Simulator which says</p>
  
  <p>Checking server...
  Connected...
  Checking server... and so on again and again</p>
  
  <p>The connection is established to the MAC and the MAC agent starts successfully. I am even able to deploy the application to the device but when I want to use the simulator this bug occurs.</p>
  
  <p>Has anyone come across this issue? Thanks.</p>
