404 error with custom urls

[maximus1127]

Hi, I have added a private folder in my storage directory. It is storage/app/encounter_uploads. I am successfully saving to this location using $encounter->addMedia($request->file('file'))->usingName($request->documentCategory)->toMediaCollection('uploads', 'private');

This saves the file to my "private" disk which I've defined in my filesystem.php file in the config directory.

My issue is that when I try to retrieve the file, I get a 404 error. I've tried to change the getUrl() function to match my root but that still doesn't work. Here is my attempted method rewrite:

  public function getUrl(): string
    {
        $url = $this->getDisk()->url('/app/encounter_uploads/'.$this->getPathRelativeToRoot());

        $url = $this->versionUrl($url);
        return $url;
    }

This correctly returns the exact path of my file, however it still gives a 404 when I put that URL as the href of an tag. I can't use a symlink here as these are private files that I don't want being accessible via the public folder. I realize that may be my issue and if it is, can someone point me in the right direction on accessing files in a private directory that is not sym-linked to the public folder?
