"Access key is empty" error when using Storj-hosted S3 gateway

When using Storj with the generated S3 credentials and the hosted S3 gateway (MT), I keep getting an XStorjAccessKeyEmpty error when sending a PUT request to a presigned URL. My credentials are absolutely correct, and I’ve even tried regenerating the bucket and the access key several times.

Using the aws-sdk-go-v2 Go package.

Can you open a support ticket on https://supportdcs.storj.io/ with the specific presigned URL that is failing for you?
