Cannot Connect my Robot app to orchestrator

[KavinduPerera]

I’m trying to try developing in older version (2019) in UiPath studio. I have got the enterprise trial version to do that and when i try to launch ui path studio it says to connect robot first.

Once I’m trying to connect my robot to orchestrator it gets a error

Can anyone Help me about what mistake gives the error and how to connect my studio and robot to orchestrator.
Thank You

We decommissioned Robots 2019.* versions.

You need to use Robots in these versions 2020.10.* or 2021.10.* or 2022.4.* or 2022.10.*

For compatibility, check this documentation Compatibility matrix
