I don't have any idea what "Secret Server" is or does, or where it runs in relation to your OpenEdge installation.
The first thing I would do is ask the infrastructure team about their fallback plan for the upgrade. They should execute it.
If they fall back to the previous version successfully (can they demonstrate that the fallback worked as intended?) and your OpenEdge commands start working again, then you have a problem with Secret Server, not OpenEdge. And that team needs to resolve it in a test environment and prove that the resolution works before they try to implement again.
If they fall back and things don't work again, you'll need to dig deeper into the chain of events that got you to where you are. Look at logs, process/procedure output, etc.
That's all I can suggest without having any specifics.
