Trying to connect to a remote machine that doesn't have internet access. The ssh connection is working fine, but it then hangs before trying to download/scp the server

Does the remote machine have scp installed? From my observation most of the time it's provided along with the client ssh program

@joshspicer yes, the remote machine does have scp. Another user has been able to use vscode server successfully on the same remote machine.

Thanks for confirming. Would you be able to provide the full log (that way I can see what settings you have enabled, etc)?
