InvalidAccessKeyId error when using a different S3 host

[guillefix]

Hello, I am getting the following error S3 error: 403 (InvalidAccessKeyId): The AWS Access Key Id you provided does not exist in our records. when using DigitalOcean Spaces.

I configured s3cmd correctly, but it seems s3cmd is ignoring the host configuration for some of the requests, as seen in when running s3cmd --debug la --recursive

Same error here but I'm using Linode Object Storage.
Previously configuring 'website_endpoint' with '%(bucket)s' and a hard coded region was working for me.

DEBUG: get_hostname(ai-space): ai-space.s3.amazonaws.com

It's still AWS S3. Try this:

$ s3cmd --host="${S3_HOSTNAME}" --host-bucket='%(bucket)s.'"${S3_HOSTNAME}" <args>

While the S3_HOSTNAME variable is "<region>.digitaloceanspaces.com". See Setting Up s3cmd 2.x with DigitalOcean Spaces :: DigitalOcean Documentation for details.
