Process runs on one machine but not in other machine

The thing is, if I run the process on the machines I originally had in the orchestrator, the processes I have work fine, but when I try to run it on another of the machines I recently added/connected, they don’t work. And that’s where I’m getting this error.
The machines are connected and associated with the same template machine; they use the same robot (user account).
It’s worth mentioning that I’m trying to run them on unattended robots.
