Laravel Storage Filesystem and Amazon S3 gives CredentialsException

I'm trying to use Filesystem, the implementation of league/flysystem-aws-s3-v3 with Laravel 5.1. but I can get the files from S3.

So, I coded this:

$s3 = Storage::disk('s3'); $imageName = Employee::filePath() . $employee->id . '.pdf';

if (Storage::disk('s3')->exists($imageName)) { return response()->download(Storage::disk('s3')->get($imageName)); } Then I get the follow error:

CredentialsException in InstanceProfileProvider.php line 79: Error retrieving credentials from the instance profile metadata server. (cURL error 28: Connection timed out after 1001 milliseconds (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)) The credential are set on config/filesystems.php, I know are good because I can put files there.

Do you have any idea?

Thanks in advance.
