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.

Exception Details: System.Threading.Tasks.TaskCanceledException: A task was canceled.

Many thanks

did you have any luck with this issue? I’m having the same problem where the connection stops working the exact same way. Thanks!

UPDATE: For anyone with the same issue, i solved the issue by explicitly adding a webproxy to the httpclienthandler of the httpclient. our devices live behind a proxy so this is required to get the traffic going out in the right direction.
