Backup to S3 Bucket at scaleway failes with "Access denied"

I want to backup the DBs to a S3 bucket at
I added a S3 Compatible Backup Connection using follwing settings:

s3 compatible
Key: added API Key generated on scaleway
Secret: added API Secret got from saleway
Bucket: bucketname
Region: fr-par

Then added Backup to Server using this profile, but get an error:

ERROR : Attempt 3/3 failed with 1 errors and: AccessDenied: Access Denied.
	status code: 403, request id: txc2f5de33301b4e429df08-00651be24d, host id: txc2f5de33301b4e429df08-00651be24d

Here is used an option “scaleway” for provider: Migrating Object Storage data with Rclone

Hello Roman,

We have not yet had the opportunity to test Scaleway, however we plan to do so in the near future. Once we have done so, we will update our documentation page with the results at Backup Profiles - Cleavr docs and will be sure to inform you of our findings.

Thank you, it worked. It seems that I had the wrong Scaleway-API -Key, however this happend. Sorry for that.
