Unable to connect to vscode server, scp: No such file or directory-CodePudding

Problem

I have a server (a shared HPC) I used to be able to connect to which I am not longer able to connect to.

Based on logs I suspect SCP may be an issue, but I am not sure as it works on my machine for other files (scp'd to the same server)

Steps taken to try to resolve the issue

Downgrade the Remote SSH extension to v0.70.0
Completely uninstall and re-install vscode on my local machine

Additional Relevant details

Personal Machine: MacOS Monterey Version 12.2.1

Upgraded Remote-SSH extension back to most current version

Took two attempts to work. If anyone knows what the issue was I would be grateful for your help so i can be sure it does not happen again!
