Huddle comes with a list of prerequisite URL's that need to be permitted (sometimes organisations will need to permit certain URL's for security reasons to help prevent unauthorised access to their networks). If this has not been completed you may experience problems using Huddle, such as problems viewing your Huddle Dashboard properly.
You can ask your network administrators to do this, the list of prerequisites to send to your administrators can be found here:
