D10 - private file system

The file can be accessed successfully under Drupal9, but NOT on Drupal10

Unfortunately this bug report is not actionable as written. Please add to this bug report the steps to reproduce. Those steps must explain how the file is displayed on content to which the current user has access, and must be reproducible by others—in most cases that means these should begin with installing Drupal. That information needs to be here, in this bug report.

Getting the file with file:/// is irrelevant.

Getting the file with file:///... means that the file itself can at least be read and processed o.k. outside of Drupal through any browser. It would be great if somebody DID look at the description of the problem in my Forum entry - as given in the Issue. Very frustrating - preventing me from migrating to D10!

I understand the frustration but bug reports must have information to have the bug fixed.

The file is displayed within a "long text-field" of a page like so:

...
  <div class="rmaudio">
    <audio controls="controls">
      <source src="/system/files/2022-02/rainermarschAusgeblendet_0.mp3" 
      type="audio/mpeg">
    </audio>
  </div>
...

Hello,
I should apparently apologize! I forgot to specify "private file system" for the storage location of the audio file. Sorry!
