Description of my issue:
I do use Akeeba Backup now for year to backup to Amazon S3 cloud - without any configuraton problems ever.
Now, Amazon changed the user management. And for some reason the backups won't upload to Amazon any more. - I guess the reason is some misconfiguration of the IAM user.
Is there a step by step tutorial on how to setup an IAM user (user group, policies). I feel somehow hopelessly confused on this.
I tried all steps in the Amazon S3 troubleshooter manual - without success. Still get this ambivalent error message back from AWS:
"Upload cannot be initialised. Amazon S3 returned an error message: 0 :: Akeeba\Engine\Postproc\Connector\S3v4\Connector::startMultipart(): [0] The request signature we calculated does not match the signature you provided. Check your key and signing method. ..."
Thanks for any hints.
Kind regards,
Bernhard
