When uploading multiple images then without saving images 403 error appered - laravel

Question

I'm uploading multiple images on server but instead of saving images in database and folder a 403 error occured. so please help me how to resolve it.
This is the Form & Controller code:
<form method="POST" action="{{ route('AddImages') }}" id="smart" enctype="multipart/form-data">
#csrf
<input type="hidden" name="id" value="{{$id}}">
<div class="form-body">
<div class="form-row">
<div class="section col-6">
<label for="bname" class="field-label">Image</label>
<label for="bname" class="field prepend-icon">
<input type="file" name="image[]" class="gui-input" multiple required>
<span class="field-icon"><i class="fas fa-circle"></i></span>
</label>
</div><!-- end section -->
</div>
</div><!-- end .form-body section -->
<div class="form-footer">
<button type="submit" class="button btn-primary"> Save</button>
<button type="reset" class="button"> Cancel</button>
</div><!-- end .form-footer section -->
</form>
$images = $request->file('image');
$num = 0;
foreach ($images as $im) {
$files = $im->getClientOriginalExtension();
foreach ($request->image as $file) {
$image = new ClassImage();
$file_name = time() . rand(1, 999) . '.' . $file->getClientOriginalExtension();
$path = base_path('backend/images/class_images/');
$image->image = $file_name;
$image->class_id = $request->id;
try {
$file->move($path, $file_name);
$image->save();
$num++;
} catch (Exception $e) {
echo $e;
}
}
}
return redirect('ShowImages/'.$request->id);
I don't know what is the error in this code because on local server this code working fine but on server the problem 403 (Access denied) Occured.
