You may find the full address in the address bar when you are on Orchestrator Tenant page. Without providing the full address in this form you will get this error:
I tried your example, but I still get a “System.OperationCanceledException: The operation was canceled.” error. I used the “Learn how to connect” example on the cloud platform to create my program, but it still won’t work
Probably you have something wrongly configured. Please give us more details like robot configuration and configuration of robot and computer on Orchestrator.
On my side I’m facing to an other error, and I don’t know where is the problem (as you can see below) because the “domain\username”, machine name, URL and machine key are right.
