Per-repo github pages work, but main github pages don't

Question

I used github pages for a project and it worked fine:

The gh-pages branch of a repo lets me load it's contents just fine

However, now I want to use the main per-person github pages it doesn't seem to want to work:

https://github.com/jnvsor/jnvsor.github.io should lead to http://jnvsor.github.io/ but while apgtk branch gh-pages works fine the jnvsor.github.io repository isn't working at all.

What's wrong?

Answer 1

github.io crashes building a page if the submodule uses an ssh url. Apparently they don't support it. Changing my .gitmodules to use https fixed the problem
