Keeps timing out on certain files

[LurkerHub]

Gallery-dl consistently times out on certain files that are accessible using the web interface. For example:

This happens even if I stop gallery-dl and retry later, always on the same files.

Gallery-dl consistently times out on certain files that are accessible using the web interface.

Are you sure that these files are the same?

The images on the site are previews (https://kemono.party/thumbnail/data/...), while gallery-dl downloads the original files (https://data6.kemono.party/data/...).

[AlttiRi]

Yes.

Currently, the original file https://kemono.party/data/3c/86/3c86a1ff6637078812ec8b5fad4daafba811cbbaa48324b862a2430aaba4fb1d.png?f=Page-5e.png is not available.

While the preview https://kemono.party/thumbnail/data/3c/86/3c86a1ff6637078812ec8b5fad4daafba811cbbaa48324b862a2430aaba4fb1d.png is loading OK.

Hmmm... Is there a way to tell gallery-dl to download the preview when the image is not available? Sort of a fall-back?

[AlttiRi]

Just rerun it later, when the CDN server backs to work.

Now those URLs are online (available).
