Cannot Remote-SSH to windows host on VSCode-CodePudding

I am attempting to connect to my local windows machine via ssh on VSCode.

It connects instantly from the CLI directly:

➜  ~ ssh windows
johnpc@DESKTOP-U5QAQJ4 MINGW64 ~
$ ls
# my windows files appear

The windows host is configured in my ssh config as follows:

Host windows
    HostName 192.168.7.208
    User johnpc
    IdentityFile ~/.ssh/id_rsa

However, when I attempt to connect to this host using the Remote-SSH VSCode extension, I get the following output, followed by a "connection timed out" error.

Any ideas what might be going on? Feels especially weird because the messages look like everything is succeeded, but still emit as stderr? stderr> Authenticated?

I figured it out (kind of). Remote-SSH only seems to work if Powershell is configured as the default ssh shell in windows.

On the windows machine, I had to run:

New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -PropertyType String -Force

Previously, I had been using git-bash as the default terminal (which is what I'd prefer):

New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Prog
ram Files\Git\bin\bash.exe" -PropertyType String -Force

Now every time I log in I have to run & 'C:\Program Files\Git\bin\bash.exe' to reach the git-bash shell.

Have you checked your Firewall/Antivirus?

A Timeout would appear if there is no answer, even if local. (Please be carefull if you want to disable your Firewall complete for testing.)
