title: client constantly reconnecting
body: <p>My .net application which connects to signalr hub is constantly reconnecting. </p>
  
  <p>This problem only occurs on certain other corporate networks which makes me believe something is being blocked.
  I've tried to use the jabbr.net website from the same network and this doesn't work either (in chrome).</p>
  
  <p>How can i trace/fix this issue?</p>
