Additional info:

when following the baseurl path to http://download.fedoraproject.org/pub/fedora/linux/releases/ it is noted there is an additional subfolder for every mirror (e.g. http://download.fedoraproject.org/pub/fedora/linux/releases/test/24_beta) if you uncomment and modify the baseurl it works.
