Server: Some files are not shown on publicly shared links

[tomynr1]

I want to share a folder with 237 files. If I am logged in, all the files are shown as expected in my NC account. Once I create a shared link, only 21 of the files are visible in browser, but if I select all the files, the correct number of files is shown.

Steps to reproduce

1. Create a folder with a lot of files (>200)
2. Share the folder by public link
3. Check if all the files are shown after accessing the shared link

Expected behaviour

Show all the files via shared link like I see when I am logged in.

Actual behaviour

Only some of the files are shown in the browser, however by selecting all the items via the 'Select all' checkbox, the correct number of files is shown. If I have photos in the folder, I can go through all of them with the arrow keys, even if they are not shown in the file list.

Browser log

I have no experience how to get these logs. Could you please provide me step-by-step advice to get them? I'm using Brave, which is in principle like Chrome.

Further Information:

• My NC instance is behind a reverse proxy
• I am behind Cloudflare
• By toggleing list or miniature view, a different number of files is shown.
• The shown files are all from the beginning of the whole list (sorted alphabetically)

Thank you @JSoko.

Deactivating Talk is definitely a solution for me, as I don't use it every day.

Is there another way also for the heavy Talk users?

[JSoko]

I didn't proofed but I hope this pr will fix it:

Problem persists with NC 17.0.1 and Talk 7.0.1
