Tenho um site onde os arquivos mp4 estão retornando 404.

Eles têm `authorized_extensions` definido como `*`. O upload do arquivo funciona perfeitamente. Eu o vejo no sistema de arquivos. As permissões estão corretas. `file` diz que é um arquivo MP4. O registro no rails parece OK:

```plaintext
[1] pry(main)> u=Upload.find(196082)
=> #<Upload:0x00005601a1b56348
  id: 196082,
  user_id: 1,
  original_filename: "PXL_20220617_184736219.mp4",
  filesize: 9328093,
  width: nil,
  height: nil,
  url: "/uploads/default/original/3X/5/6/5679d94dfce852f780afa5fcb7f1a29d810cc8fc.mp4",
  created_at: Fri, 17 Jun 2022 18:53:41.130790000 UTC +00:00,
  updated_at: Fri, 17 Jun 2022 18:53:41.176664000 UTC +00:00,
  sha1: "5679d94dfce852f780afa5fcb7f1a29d810cc8fc",
  origin: nil,
  retain_hours: nil,
  extension: "mp4",
  thumbnail_width: nil,
  thumbnail_height: nil,
  etag: nil,
  secure: false,
  access_control_post_id: nil,
  original_sha1: nil,
  verification_status: 1,
  animated: nil,
  security_last_changed_at: nil,
  security_last_changed_reason: nil>

```

mas acessá-lo retorna um 404. Houve alguns novos recursos e correções de bugs para mp4 recentemente, mas acabei de fazer um upgrade e ainda não está funcionando. Não sei mais onde procurar.
