Laravel 5.3使用AJAX错误上传52张图像

I have a problem. I'm using Bootstrap fileinput to upload 52 images with async AJAX requests. It uploads 90% of the files and randomly gives errors on few of the images.

This is the error:

SQLSTATE[HY000] [1045] Access denied for user 'forge'@'localhost' (using password: NO)

Upload function:

public function uploadTemp360(Request $request)
    $image = $request->file('view360s');
    $fileName = $image->getClientOriginalName().'.'.$image->getClientOriginalExtension();
    $path = public_path().'/uploads/temp/';

    if ($image->isValid()){
        $image->move($path, $fileName);

    return [
        'initialPreview' => [
            "<img  style='height:160px' src='/uploads/temp/".$fileName."' class='file-preview-image'>",
        'initialPreviewConfig' => [
            ['caption' => $fileName, 'width' => '120px', 'url' => route('admin.products.delete-temp-360'), 'key' => $fileName, 'size' => \File::size($path.$fileName)],
        'append' => true,
        'filename' => $fileName,

I don't know what's going on and how is it causing DB error by running this code...

I have found in laravel log this error: production.ERROR: exception 'RuntimeException' with message 'The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths.'

    I have fixed that issue with running command: php artisan config:cache. It was problem because of Laravel can't read .env file sometimes...

    It seems your database connection is being closed. Using following code you can keep you connection alive after each image upload.

    This could be a problem with the Laravel app key. Try executing these two commands in the following order using the command line from your projects root directory:

    php artisan key:generate
    php artisan config:clear

    You can also try making sure that in your config/app.php file you have the following and try to clear the config again:

    'cipher' => 'AES-128-CBC',
