Failed to upload updates - AWS

Hi,Ive been uploading the update files to AWS via web browser because Ive been receiving the following error every time."The specified bucket does not exist. Skipping the next 9 files" I'd rather be able to use Wybuild to update if possible please.Server type: amazon s3Bucket: myappname.desktop.updates.com.s3-website-eu-west-1.amazonaws.com(Ive tried both the above and also stuck the http:// in front of it just in case, not working still)Directory: FilePublish/myappname.allaccesskey: blahdeblah, secret key: boobooboo

If I test and enter the whole address into a web browser it works fine to download filesWhat am I doing wrong please?
