Disk named do-spaces cannot be accessed

I have already configured my disk spaces in Digital Ocean Spaces, which worked fine till yesterday. However, after my latest deployment, I encountered the 'disk cannot be accessed' issue. Below is my setting, which worked before.

But this works fine on my local computer. When I deploy to my production server, it triggers the above error.

'do-spaces' => [
            'driver' => 's3',
            'key' => env('DO_ACCESS_KEY_ID'),
            'secret' => env('DO_SECRET_ACCESS_KEY'),
            'region' => env('DO_DEFAULT_REGION'),
            'bucket' => env('DO_BUCKET'),
            'url' => env('DO_URL'),
            'endpoint' => env('DO_ENDPOINT'),
            'use_path_style_endpoint' => env('DO_USE_PATH_STYLE_ENDPOINT', false),
            'throw' => false,
            'bucket_endpoint' => true, 
            'root' => 'skmdd/media',
            'visibility' => 'public',
        ],

When I set throw to true, I get this issue
