理由はわかりませんが、ルーターの接続が毎日ほぼ同じ時間に切断されます。
何が起こっているのか誰か知っていますか?

答え1
質問のコメントで指摘されているように、接続はピアによって終了されているようです。つまり、ISP が接続を終了しているということです。また、これは接続が確立されてからちょうど 24 時間後に発生するため、ISP による強制的な切断が示唆されます (これは、IP アドレスが 24 時間ごとに変更されるようにするための措置で、これにより、自宅のネットワークでサーバーを実行するのが少し困難になります)。
別の時間にルーターを切断または再起動し、切断がいつ発生するかを確認します。切断が操作後 24 時間後に発生する場合 (以前に確認した時間ではなく)、これは ISP が 24 時間ごとに切断していることを示すもう 1 つの兆候です。
