VScodeのremote - ssh が繋がりません。

#環境
サーバー: windows server 2019
クライアント　: mac os
ssh : OpenSSH_8.1p1, LibreSSL 2.7.3
vscode : Version: 1.49.0

現在初めてサーバーでの開発を行おうとしています。

VSCodeのremote-sshを使ってみたくてssh公開鍵認証を設定しました。
ターミナルからのsshコマンドでは接続できるようになっています。

次にvscoddeにremote-sshを入れて「さあ、やるぞ！」ってなったのですが、接続ができません。
お力をお貸しください。

長いですが、接続しようとしたときのoutputです。

結果は

Could not establish connection to "118-27-78-43": The VS Code Server failed to start.

Server did not start successfully. Full server log at C:\Users\Administrator.vscode-server.e790b931385d72cf5669fcefc51cdf65990efa5d.log >>>
とあったので、logがあるかなと開けたら中身は空でした

いまいち、何が原因かも読み解けません。
Starting server with command... & 'C:\Users\Administrator.vscode-server\bin\e790b931385d72cf5669fcefc51cdf65990efa5d\server.cmd'
これを実行して失敗ってことなんでしょうか？
