ドメイン名がVPSに解決されない

Cent OS 7 で DO VPS を実行しています。nginx と Virtual min をインストールしました。ドメインを VPS に解決できません。cloudflare でフローティング IP (静的 IP) を指す A レコードと、値 @ を持つ CNAME www を作成しました。以前と同じ設定を使用していましたが、機能していました。ドロップレットを破棄して再構築しましたが、VPS に同じ静的 IP を割り当てました。ポート 80、443、10000 を許可しました。

私も nginx.conf をポート 443 でリッスンするように設定しました。しかし、それでもドメイン名が VPS に解決されません。これが私の nginx.conf です。

netstat -an | grep 443 | grep -i listen を使用してポートが listen しているかどうかを確認してみましたが、 listen しているようです。出力は次のとおりです。

 tcp        0      0 174.138.xxx.x:443       0.0.0.0:*                     LISTEN
