Error to connect uirobot with orchestrator

I am taking course “Orchestrator 2018.2 training” because I want to understand how orchestrator works so that I mange all my robots using it.

However, when I configured uirobots settings appeared the following error message


someone knows, how can I solve it?

Uipath version installed is 2018.1.4

Hi, what was the action you were trying when you got that message? Seems like you have an on premises orchestrator right? But i see the community edition cloud url being used in that message… Also maybe you wll want to take the course for the 2018.1 version.
