We are currently addressing an issue affecting some AWS VM backup jobs. Impacted jobs may fail during processing due to a signature validation error encountered while accessing data through the AWS API. We have identified the root cause and are actively deploying a fix to the affected systems. We will provide another update once the deployment is complete and service has been fully restored. We apologize for any inconvenience and appreciate your patience as we work to resolve this issue.
