Not sure, but I think you need a CNAME file on github advertising your host name.

http://ns.science.ai is a github page. As far as i can tell, HTTPS is not supported for GitHub Pages using custom domains but maybe this has changed ?

https://gist.github.com/cvan/8630f847f579f90e0c014dc5199c337b explains how to do it with CloudFlare (free) and CNAME.
However, I don't think https is necessary in this case. I only tried it in relation to #24
