Amazon S3 Credential issue

Running Scale Dragonfish-24.04.0, I get an error when verifying S3 credentials. I am getting the following error:

 Error: <5>NOTICE: s3: s3 provider "" not known - please set correctly
<3>ERROR : : error listing: AccessDenied: Access Denied
	status code: 403, request id: NVZDVBS0C8EBSYSR, host id: HqAJaZFoQouDrofI8ohtPyIPcVQx5lFxWhU2updx+Wfo+lmAZWlCiuHYRnrVEN2BzNG2zthPiNY=

I have attached a policy to an AWS IAM user (see below) that I had used previously with a Synology system for backups to the depricated Glacier vaults.

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Sid": "CCCTVArchive",
			"Effect": "Allow",
			"Action": "s3:*",
			"Resource": [
				"arn:aws:s3:::bucketname/*",
				"arn:aws:s3:::bucketname"
			]
		}
	]
}

I created a fresh set of access keys for the IAM user and put those in the appropriate place in the Backup Credentials GUI. Any help would be appreciated.
