Safari 15.6.1 (macOS catalina) could not display pdf file properly.

[drzchang]

Describe the bug/problem

I run a docker instance (linuxserver/calibre-web:0.6.23-ls281), and the pdf file content cannot display properly (nothing displayed) in Safari 15.6.1 (macOS catalina) while Chrome work well in the same MacBook pro.
This problem not only exist in this version, but also the previous versions (0.6.21 and 0.6.22).

I'm wondering it's related to calibre-web or linuxserver/calibre-web.

There have been reports that older Mobil OS versions aren’t working properly. Like here: mozilla/pdf.js#18222
Could you please check if there is some error on the developers console in the browser visible?

And could you please check if both pdf files in the link are working/not working for you?

I'm not familiar with web development, so I'm not sure if this is what you are looking for.

Additional notes:
I can open the same pdf file in the safari browser of my iPhone with iOS 17.6, and old safari in old macOS (catalina) cannot work.

The PDF 1 link on the page https://test2.bannersky.com/bsk-pdf-manager/ use the old version 4.3.136, it CANNOT be open.

I don't find any pdf link in this link.

The PDF 1 link on the page https://wangjingtang.com/bsk-pdf-manager/ use the old version 4.0.379, it CAN be open.

work.

You are right, I had a conversation a few weeks ago, there the first link also had a pdf file in it. Anyway, the first screenshot was what I was looking for, and google had a good idea what to do.

Please try to update to the newest nightly version. I changed the pdf reader, for me both version were working, so I'm not sure (but quit confident) that it will work afterwards

I also encountered the same problem with Docker container: linuxserver/calibre-web:0.6.23-ls281. I couldn’t open PDF in Chrome, Firefox, or Edge. Finally, I solved it by installing the nightly version. Thank you.
