 Several of our buckets are configured to automatically encrypt uploaded
 files using Server Side Encryption and a KMS key. When attempting to
 download these files using Cyberduck, we consistently get the above error:

     Requests specifying Server Side Encryption with AWS KMS managed keys
 require AWS Signature Version 4. Please contact your web hosting service
 provider for assistance.

 We are making sure to connect to the S3 endpoint that matches the region
 for the bucket (in this case, s3-us-west-2.amazonaws.com).
