I was running 3 robots on one server (hight-density configuration) and everything was working fine until I had to change the password of the session used by one of the robot for security purpose.
Since then, I am consistently getting this error when I try to start this robot:
“Executor start process failed, reason System.Runtime.InteropServices.COMException (0x80070520): A specified logon session does not exist. It may already have been terminated”
All the other robots are working just fine, RDP session connected to the server or not.
The password for the robot should be the right one since i am getting the “Logon failure: unknown user name or bad password” error when I try with a wrong password.
I have try to sign off every RDP connection with no result
I have try to update the UiPath Robot to 2018.4 since I saw that it should seemed to solve the problem, but no change.
Do I also have to update Orchestrator (from 2018.1 to 2018.4) to get the fix?
Any idea to solve this would be welcome
