channel 3: open failed: administratively prohibited: open failed が解消されません

Question

VS Code Remote Development SSHセットアップで困ってます

要件

SHHを使用してVSCからサーバーにリモートアクセスを試みましたが、

channel 3: open failed: administratively prohibited: open failed
channel 4: open failed: administratively prohibited: open failed

で失敗してしまいます。
また以下も表示されます。

リモート拡張ホスト サーバーへの接続に失敗しました (エラー: WebSocket close with status code 1006)

やってみたこと

/etc/sshd_configを編集してAllowTcpForwardingとPermitOpenという設定項目を

AllowTcpForwarding yes
PermitOpen any

に書き換える

再起動もしてみましたがダメでした。
ローカルでは接続は確認できてます
