Unable to upload from URL

[CodeCures]

I don't know if this package has the functionality but, i'm trying to upload an audio file using an absolute path to the file on the internet but it keeps saying that file is not found

$filestack = new FilestackClient(config('services.filestack.key'));
$response = $filestack->upload('https://www.soundhelix.com/examples/mp3/SoundHelix-Song-9.mp3', [
    'filename' => $lesson->name
 ]);

Here is the error message

Please how can this be fixed
