Velero 1.14.1 & aws plugin 1.10.1: api error SignatureDoesNotMatch

[amrap030]

What steps did you take and what happened:

When using velero version 1.14.1 and the AWS plugin version 1.10.1 I always get the following error when creating a backup:

When I look into my S3 bucket with a viewer, I can see that there is a folder /restic created with all the expected files. However, the folder /backups is missing.

What did you expect to happen:

I expect the backup to complete without failures with a folder called /backups and its content.

The following information will help us better understand what's going on:

If you are using velero v1.7.0+:
Please use velero debug --backup <backupname> --restore <restorename> to generate the support bundle, and attach to this issue, more options please refer to velero debug --help

If you are using earlier versions:
Please provide the output of the following commands (Pasting long output into a GitHub gist or other pastebin is fine.)

• kubectl logs deployment/velero -n velero
• velero backup describe <backupname> or kubectl get backup/<backupname> -n velero -o yaml
• velero backup logs <backupname>
• velero restore describe <restorename> or kubectl get restore/<restorename> -n velero -o yaml
• velero restore logs <restorename>

Anything else you would like to add:
