Disconnects immediately when adding folder as a workspace -- yet connecting via terminal works fine.
User can open VS Code and use the 'Open remote SSH terminal' option in SSH FS to connect. That works.
User tries to 'Add as Workspace folder'. Fails. Looked at the /var/log/messages and /var/log/secure, it's apparently successfully authenticating the user, then immediately disconnecting. I'd think the user didn't have a shell or something, but they can connect via the terminal in SSH FS and it's fine.

Appears to have been some Cyberark issue, but still not understanding fully why it would allow a normal SSH terminal connection through VS/SSH-FS, and not adding a folder as a workspace.
I don't dev this extension, but it could possible be due to a change in the VS Code API when adding folders to the workspace.
Does this issue still occur?
While the sftp subsystem call failing with a status code 255 doesn't tell me much, the little what I can find about it mentions the user not having configured a proper terminal. Since you can still create a terminal, that shouldn't an issue (unless you changed SFTP Command or Terminal Command or similar).
Does SFTP work outside the extension? Perhaps running the subsystem (or /usr/lib/openssh/sftp-server which OpenSSH uses) got blocked by Cyberark.
It was some sort of configuration issue on the CyberArk side they resolved. That's another team/division from where I'm at, so unfortunately I don't have a lot of insight into what they actually changed.
SFTP was working outside the extension, from a normal terminal prompt, yes.
Then I'll assume it's a security feature based on e.g. the SSH client's ident (SSH-2.0-ssh2js) or similar, hard to diagnose/fix at this point. I'll close the ticket since that team figured out what's causing it on their end.
