### Verlängerung des Zertifikats

Irgendwann in der Zukunft würde jedes Zertifikat **ablaufen** (etwa 3 Monate nach dem Erwerb).

Und dann gäbe es ein anderes Programm (in manchen Fällen ist es ein anderes Programm, in manchen Fällen ist es derselbe TLS-Terminierungsproxy), das mit Let's Encrypt kommuniziert und das/die Zertifikat(e) erneuert.

Die Statuscodes im 400er-Bereich bedeuten hingegen, dass es einen Fehler gab.

Erinnern Sie sich an all diese **404 Not Found** Fehler (und Witze)?

## `HTTPException` verwenden

Um HTTP-Responses mit Fehlern zum Client zurückzugeben, verwenden Sie `HTTPException`.
