Run Agent (Preview): Response status code does not indicate success: 403 (Forbidden)

Hi Team, I’m getting following error while I run the agent from a BOT using Run Agent activity.

Details: I’ve designed a BOT that run that invokes An agent. Its running fine in attended mode. But while I run it in unattended mode, its shows below error. Could someone help me on this…?

Error Message: Run Agent (Preview): Response status code does not indicate success: 403 (Forbidden).

Hi @sureshkumar.s

Check if the unattended robot has the correct permissions in UiPath Orchestrator. Go to Orchestrator → Roles, ensure the robot has permissions to run unattended processes.

Verify that the machine template and robot are properly assigned. Check Machines and Robots in Orchestrator to confirm the correct mapping.

Ensure the agent supports unattended execution. Some agents require specific configurations to run without a logged-in user.

Try running UiPath Robot as an administrator. Right-click the UiPath Robot tray icon, select Run as administrator, and check if the issue persists.

If you found helpful mark as a solution tick.

Happy Automation
