Additional notes:

• The issue cannot be reprocued on another instance using the same image.
• Disabling the apps which aren't enabled on the other instance did not help
• First I thought it's related to [Bug]: Files shared via Public Share Links no longer accessible (HTTP 401) server#43287 - but it also exists on 28.0.4 and federation sharing is enabled.

[Bugsbane]

One extra bit of info: I have this issue too, but removing special characters (such as hyphens) from the file name seemed to work around the issue.

[bjo81]

@Bugsbane Interesting, as I got the issue also with Nextcloud Manual.pdf which apparently has no special characters.

[R053NR07]

I get this issue when "hide download" is activated. If not it's loading.

[Bugsbane]

@Bugsbane Interesting, as I got the issue also with Nextcloud Manual.pdf which apparently has no special characters.

I would suggest trying to remove the space between "Nextcloud" and "Manual" and see if it still happens...

Does not help.

[Mer0me]

Some news here ? I've set Onlyoffice as default app to open PDF and disabled files_pdfviewer temporarly as a workaround, but the files_pdfviewer reader is much reactive and I would like to revert as soon as possible.

seems related to #649

Screencast.from.2025-06-15.12-34-53.webm

Same issue this side Nextcloud 31.0.5 (snap) on Ubuntu 24.04.2 LTS (server)... If i share a PDF (or folder with PDFs) with "Hide download" enabled it simply keeps loading and never opens, when i disable "Hide download" the pdf opens normally.

Hide download enabled on a public share behavior
Expected behavior: Preferably the PDF preview opens but does not allow the user to download the file. OR. Show the user an error message, warning them that Hide Download has to be disabled to view the PDF like in #649.
Actual behavior: The preview never opens, and keeps loading forever.

Tested in both Firefox, Safari, Chrome and Edge, the issue is present on all my devices, from iPad, Mac, Ubuntu desktop, Android and Windows which have no common app/extensions installed.

Public share with "Hide download" enabled: https://jacksonserver.ddns.net/index.php/s/NYJXzCHNHft2okc
Public share with "Hide download" disabled: https://jacksonserver.ddns.net/index.php/s/t5jXMBtKA48jxcH
Note, both public shares above are for the same file.
