How to get Spaces pre-signed URL working with CORS?

I’m trying to upload a file using Vue+axios by generating a pre-signed URL on my server and then using that URL to attempt a PUT.

Unfortunately I constantly get request has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. even though I’ve configured my CORS as loose as possible:

Methods: GET, PUT, DELETE, HEAD, POST
Headers: Access-Control-Allow-Origin, Access-Control-Request-Headers, Access-Control-Request-Method, Origin, Referer```

I've also tried with * as the Headers value and putting my prod domain (I had hoped the above would work on localhost). It also doesn't work for my prod domain.

Any idea on how one can get this to work?

Thanks
