Thanks for taking the time to open an issue. A couple follow up questions:

scp is a "fallback" mode when the remote host cannot download the necessary VS Code server itself, seen at:
```
> Downloading with wget
> wget download failed
> wget: unable to resolve host address 'update.code.visualstudio.com'
```
Is this host blocking outgoing requests in such a way that this makes sense? One way to unblock yourself is allcowing the remote host to reach this domain.

Are you able to manually scp between your host and the remote machine? For example, the command that I see in your log is

"C:\WINDOWS\System32\OpenSSH\scp.exe" -F "C:\Users\ayebdh\.ssh\config" "vscode-server.tar.gz" "vscode-server.tar.gz.done" sldafrm32ba01:"/users/ayebdh/.vscode-server/bin/f1a4fb101478ce6ec82fe9627c43efbf9e98c813"

Looking at the scp error

[14:30:39.123] > Authenticated to sldafrm32ba01 ([100.78.1.46]:22) using "keyboard-interactive".
[14:30:39.156] > C:\WINDOWS\System32\OpenSSH\scp.exe: Received message too long 458961211
[14:30:39.193] > C:\WINDOWS\System32\OpenSSH\scp.exe: Ensure the remote shell produces no output 
> for non-interactive sessions.

The error message Received message too long 458961211 indicates that there is unexpected output from the remote shell, which interferes with the scp command. This can happen if there are commands in your shell profile files (like .bashrc, .bash_profile, or the windows equivalents) that produce output. I've searched around a bit and it seems like a relatively common problem - here are some steps you can try: https://www.websentra.com/troubleshooting-received-message-too-long/
