Hi
Make sure that bot is installed in service mode and not in user mode
Only then you will be able to access the elements in unattended mode
For more details
To check how is your robot deployed you need to check your Windows services and check under which user it’s working. If it’s your username then you need to reinstall your robot using the msi package.
And if you are trying to run or connect from orchestrator then make sure that in robot setting it is set as false in log in to console
