TaskCanceledException

Hi

I’ve just started with okta, and to do so have taken the example .net app and got it running on my local machine without too much of a problem. I’ve then copied it to a Web host and changed the Okta application and web,config to reflect the new URLs, to share and discuss with some colleges . The MVC site shows ok, but when clicking login I get a “TaskCanceledException”. Any one got any ideas what it could be? Here’s the full set of exceptions given:
Server Error in ‘/’ Application.
A task was canceled.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
