scp -rを使用してファイルを転送しようとすると、権限が拒否されました。

このコードを実行するとエラーが発生します。

 scp  -r ./build/* rose@IP_address:/var/www/mywebsite.com/html

Permission denied(publickey)
lost connection

最初は機能しますが、create-react-app Webサイトにいくつかの変更を加えようとすると機能しません。

これは断片です

scp -vvv  -r ./build/* rose@IP_address:/var/www/mywebsite.com/html
