העלאת קובץ גדול לא עובד

[121244]

יש לי קוד שאמור להצליח לעלות גם קבצים גדולים ומשום מה בשלב של החיבור זה נתקע
מצורף הקוד והפלט אשמח לעזרה @שמואל

<?php
// פרטי התחברות והגדרות
$token = ':'; // מספר מערכת וסיסמה או API_KEY
$localFilePath = 'file.mp3';    // הקובץ שברצונך להעלות
$remotePath = 'ivr2:567.wav';   // הנתיב במערכת
$chunkSize = 10 * 1024 * 1024;  // גודל מקטע (10MB לדוגמה)

$fileName = basename($localFilePath);
$totalFileSize = filesize($localFilePath);
$qquuid = bin2hex(random_bytes(16));
$totalParts = ceil($totalFileSize / $chunkSize);

$handle = fopen($localFilePath, 'rb');
if (!$handle) {
    die("Cannot open local file");
}

for ($partIndex = 0; $partIndex < $totalParts; $partIndex++) {
    $offset = $partIndex * $chunkSize;
    fseek($handle, $offset);
    $chunkData = fread($handle, $chunkSize);

    // שמירת החלק כקובץ זמני
    $tmpFile = tempnam(sys_get_temp_dir(), 'chunk_');
    file_put_contents($tmpFile, $chunkData);

    $postFields = [
        'token' => $token,
        'path' => $remotePath,
        'qquuid' => $qquuid,
        'qqpartindex' => $partIndex,

        'qqfilename' => $fileName,
        'qqfile' => curl_file_create($tmpFile, 'application/octet-stream', 'part')
    ];

    $ch = curl_init('https://www.call2all.co.il/ym/api/UploadFile');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);

    $response = curl_exec($ch);

    if ($response === false) {
        echo "Curl error on part $partIndex: " . curl_error($ch) . "\n";
    } else {
        echo "Part $partIndex uploaded: $response\n";
    }

    curl_close($ch);
    unlink($tmpFile); // מחיקת הקובץ הזמני
}

fclose($handle);

// שליחת בקשת Done
$doneParams = [
    'done' => '',
    'token' => $token,
    'path' => $remotePath,
    'qquuid' => $qquuid,
    'qqfilename' => $fileName,
    'qqtotalfilesize' => $totalFileSize,
    'qqtotalparts' => $totalParts,
    'convertAudio' => 1
];

$doneUrl = 'https://www.call2all.co.il/ym/api/UploadFile?' . http_build_query($doneParams);
$response = file_get_contents($doneUrl);

if ($response === false) {
    echo "Error sending Done request\n";
} else {
    echo "Done response: $response\n";
}

וזה הפלט
