Jekyll problems with publishing on GitPages

Question

I have just created my first jekyll page, trying to use github.io

What am I doing wrong, as the page seems to serve correctly on my local machine yet it does not on the GitPages.

If you want to use a github.io URL, the exact URL of your GitHub page depends on the name of your repository.

This is explained here in the GitHub Page documentation:
User, Organization, and Project Pages

• If you want your website URL to be https://cstml.github.io/ (called "user page" in the docs), the repository must be named username.github.io, i.e. in your case:
  https://github.com/cstml/cstml.github.io

• If you want your website URL to be https://cstml.github.io/some-sub-dir (called "project page" in the docs), the repository must be named some-sub-dir, i.e. in your case:
  https://github.com/cstml/some-sub-dir
