Access denied to external S3 bucket configured in composition settings

Failed to upload media to the external S3 bucket configured in your account's composition settings.

Media composition has been marked as FAILED and will not be retried.

• If you have specified your own bucket and access credentials, this is most likely due to the fact that the configuration is out of date.

• In the composition settings section of your account's console, review the credentials for accessing your S3 bucket or disable the external storage (media will be uploaded to the default bucket).
