If you are configuring a distribution pointing to a S3 public bucket and you are (culr -v) getting a redirection like
<Error><Code>TemporaryRedirect</Code><Message>Please re-send this request to the specified temporary endpoint. Continue to use the original request endpoint for future requests.</Message><Endpoint>
Or the browser is rewriting the domain url with the s3 url bucket you likely have the Origin bucket named without the zone.
Simply add the zone between the s3 and amazonaws.com like in mybucket.s3.eu-central-1.amazonaws.com.
