Using the short domain name on GitLab pages on own server

I am trying to use GitLab pages on an university GitLab server instance to write a blog about my project.

Link to the repo

Link to the generated jekyll website

I would like to drop the “/blog” in the URL (https://leia.pages.rwth-aachen.de/blog/) and just use “leia.pages.rwth-aachen.de”, which seems to be the equivalent of “username.gitlab.io” on “gitlab.com”. Is this possible? How can I achieve this?

I tried renaming the repository to “leia.pages.rwth-aachen.de” and the path to “https://git.rwth-aachen.de/leia/leia.pages.rwth-aachen.de” and then changing “baseurl: /leia.pages.rwth-aachen.de” in “_config.yml”, but this just results in a 404 Error.

Thanks!
