Terminal Error : error creating terminal proxy


We are using Rocket Bluezone for our host mainframe sessions and I had configured the connection earlier and it worked fine. But then we updated the Studio and formatted the computer and I had to reinstall Rocket Bluezone. But now when I try to run the workflow, I get the error : Error connecting to terminal: ErrorCreatingTerminalProxy. Not much relevant help available on Forum on this topic. Anyone knows what’s wrong here?
