Logics have been centralised: * region to hostname * url generation * signature * chaning scheme also changes the port During the process a couple of inconsistencies have also been fixed. Known limitations: When using the @endpoint with a custom port you need to specify the port when using get_object_http_url or get_object_https_url. When using bucket names that contain dots outside of us-east-1 make sure to access it with the same region in your AWS::Storage.
