Process running perfectly from Studio and also from UiPath Assistant while VM window is open, But Timeout error when running from Orchestrator as unattended process

Hi Team,

I have completed my process development from the Studio.

While I was testing, following are my results:

  • Running perfectly end to end from Studio as an attended robot
  • Running perfectly end to end when ran from UiPath Assistant as an attended robot
  • Running from Orchestrator as Unattended robot : Getting TIME OUT ERROR as soon as first instance of selector (click/type) appears

I can see the running from Orchestrator is giving TImeout errors as soon as selectors are involved into the automation.

I was able to observe this pattern, but not sure why this is happening.

Please help ASAP as this is affecting the production deliverables!!!

Have a view on this thread and check the Service mode type

Hope it works

Hi @hacky ,

Could you please check below things first.

  1. We should have any on going connections with the VM like user logins. to avoid this we have to restart the VM to make sure that no user logged into this VM machine.

  2. Have you installed the Bot which you are running as un attended from orchestrator by using MSI installer since we must install the bot with service mode since service mode bot is required for un attended automation.

  3. Make sure that you assigned un attended bot license for the Bot(VM) which you are trying to run your process un attended.

please check above points and let us share your confirmation. thanks.


Pls have a check on these points
Hope this would help you resolve this

  1. I would strongly suggest you to follow the steps and guidance mentioned in this knowledge base which describes the same scenario you are facing
    Automation Works in Attended Mode but Not in Unattended Mode

  2. Make sure the robot installed is in service mode
    This is very essential in order to let your bot run in unattended mode and also to access the UI elements

  3. Finally Make sure the machine you developed and the machine where you are running this bot, has same resolution
    If the resolution of those machine differs then UI automation will fail
    Resolution can be set in ROBOT settings when you create your robot
    Set the same height, width properties between the machines

If you are using only one machine then it’s completely fine with this point in specific

Cheers @hacky
