403 error "The request signature we calculated does not match the signature you provided. Check your key and signing method" using strapi-provider-upload-aws-s3

I’m trying to use strapi-provider-upload-aws-s3 with Strapi v4.

When I try to upload a file I get an error: Request failed with status code 403

Here’s the error I get in the terminal: error: The request signature we calculated does not match the signature you provided. Check your key and signing method.

Any ideas what I need to change to fix this error?

Thanks
