But I get some error when I try connect Robot to OC as bellow
Please help me! i have sucked on it lots of days. :frowning:

Make sure you are passing the port along with the URL and that is 443 as it is a https server

@PaulWang24 Can you please give full computer name (which includes the domain) in the orchestrator URL field instead of http://hostname/.
Example: http://FullComputername/

Go to control panel of the server where the orchestrator is hosted to get the full computer name.

I cann’t access to OC with full computer name/computer name, like http://FullComputername/

yeah, port is 443
