S3 Bucket as Config Backup

Hi, 

currently I try to configure a SGRID S3 Bucket as a ONTAP Cluster Configuration Backup destination. 

Is it possible to backup the cluster configuration to an S3 bucket via  HTTPS? - NetApp Knowledge Base

I configured everything according to ONTAP, AWS Presign and SGRID but the backup fails. 

Access to the buckets via S3 Browser or Download of Files using Presigned URL works well. 

Has anyone in here successfully configured SGRID S3 Buckets as a Cluster Configuration Backup destination?

Regards, 

Nico
