[ROBOT] unexpected character encountred while parsing value: <, Path '', line 0, position 0

Hi there!
I’m facing this issue when connecting robot to orchestrator.

Licenses Attended Concurrent User (robot and studio)

  1. I created a floating robot
  2. I created template machine (wich machine key is used in local robot)
  3. Connect local robot to https://platform.uipath.com/[tenant]/[service]
  4. Set the machine key
  5. And then click Connect

Message:
unexpected character encountred while parsing value: <, Path ‘’, line 0, position 0.

I don’t know what can I do…

EDIT: I can’t activate studio… manually and acquire licenses not working…
