error while validating the input provided for the PutObject operation: [Bucket] is missing

I upload a image with livewire to s3 and it is work fine. the tempory file folder upload also works fine. now I move the app to production (laravel forge etc) and the upload dont works more.

i get the error :

Found 1 error while validating the input provided for the PutObject operation: [Bucket] is missing and is a required parameter

it's weird because local works and online doesn't. from my pc I can upload to s3. I inspect and I have a 500 Internal Server Error does anyone have any idea. has to do with s3 or is missing a parameter my code is:

public function createSerie() {
        if (auth()->check()) {
            $this->validate();
            Serie::create([
                'user_id' => auth()->id(),
                'category_id' =>$this->category,
                'status_id' => 1,
                'title' =>$this->title,
                'excerpt' =>$this->excerpt,
                'description' =>$this->description,
                'foto' =>  $this->foto->store('img', 's3'),
            ]);
            session()->flash('success_message', 'Uhuu');
            $this->reset();
        }else{
            abort(Response::HTTP_FORBIDDEN);
        }
    }
