PHP FPM with Nginx, unwritable file

Describe the bug

2021/08/03 21:47:35 [error] 19363#19363: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Streaming\Exception\RuntimeException: A temporary file could not be created. in /home/***/Desktop/HLS2/vendor/aminyazdanpanah/php-ffmpeg-video-streaming/src/File.php:91

To Reproduce Opened the encode.php encode.php:

<?php
$time_pre = microtime(true);
$vid = isset($_GET['url']);
if (empty($vid)) {
    $vid = '/home/***/Desktop/HLS2/1.mkv';
}
require 'vendor/autoload.php'; // path to the autoload file
use Monolog\Handler\StreamHandler;
use Monolog\Logger;
use Streaming\FFMpeg\Exception\ExceptionInterface;
use Streaming\FFMpeg;
use FFMpeg\FFProbe;
use FFMpeg\Coordinate\Dimension;
use FFMpeg\Format\Video\X264;
$config = [
    'ffmpeg.binaries'  => '/usr/bin/ffmpeg',
    'ffprobe.binaries' => '/usr/bin/ffprobe',
    'timeout'          => 3600, // The timeout for the underlying process
    'ffmpeg.threads'   => 12,   // The number of threads that FFmpeg should use
];
//$save_to = './2/key';
$time = md5(time());
$url_2 = '/home/***/Desktop/HLS2/2/'.$time.'/';
if (!file_exists($url_2)) {
    mkdir($url_2, 0777, true);
}
$url_base = 'http://localhost:80';
echo $url_2;
fopen($url_2."testfile.txt", "w");
$url = $url_base.'/2/'.$time.'/'.$time.'.key';
$save_to = $url_2.$time.'.key';
$log = new Logger('FFmpeg_Streaming');
$log->pushHandler(new StreamHandler('/home/***/Desktop/HLS/loog/ffmpeg-streaming.log')); // path to log file
$ffmpeg = Streaming\FFMpeg::create($config, $log);
$video = $ffmpeg->open($vid);
$video->hls()
    ->encryption($save_to, $url, 90)
    ->x264()
    ->autoGenerateRepresentations([1080, 720])
    ->save('/home/***/Desktop/HLS2/2/'.$time.'/part');
$time_post = microtime(true);
$exec_time = $time_post - $time_pre;
echo $exec_time.' Seconds to run';
?>

Expected behavior Render video, then just load (on load, another script takes the m3u8)

Screenshots Desktop/Server (please complete the following information):

OS: Linux
Version Ubuntu
FFmpeg vesion : Latest from APT
PHP - php 7.4.1 FPM (nginx)

Additional context This worked fine on the PHP-CLI local server, maybe FPM locked the files?

I have tried sudo chmod 777 -R * on the folder, still same issue
