Unable to read PDF files from Kiwix-serve

[Popolechien]

It used to be that a user trying to access a PDF file from their mobile phone via Kiwix-serve (either directly from library.kiwix.org or from the hotspot) would be able to read them directly and without problem.

But now trying to check https://library.kiwix.org/viewer#maitre_lucas_completer_les_mots_fr_2023-05/files/compl%C3%A9ter%20les%20mots%205.pdf from my mobile leads to this:

Phone is Nothing phone 2 running Android 14 and Google Chrome 122.0.6261.119

library.kiwix.org link works fine for me on my android. @rgaudin Do you see anything weird at http response level? Might that be that the problem is that the browser can simply nor handle properly the PDF (within the iframe)?

I can reproduce on Chrome/Android but not on Firefox/Android
