SignatureDoesNotMatch AWS With Laravel 5.1

I have a problem to list files from my bucket in S3 using Laravel 5.1. When I try , it returns the message " SignatureDoesNotMatchThe signature request, calculated does not match the signature you provided. Make sure your key and signature ." I tested this on a Java class and return Ok . Below my setup .

' S3 ' = > [
' Driver ' => ' s3 '
' Key ' => env ( ' S3_KEY ' ) ,
' Secret' = > env ( ' S3_SECRET ' ) ,
" Region " = > env ( ' S3_REGION ' ) ,
' Bucket ' => env ( ' S3_BUCKET ' ) ,
' Scheme ' => ' http '
]
:: Storage disk ( s3 ) -> files ( )

Any idea ?
