Can't enforce https for github pages with default domain

Question

I tried to deploy the site of a github repository from the associated gh-pages branch, using the default domain.

I've already done it many times but I never encountered the case where the checkbox "Enforce HTTPS" could not be checked (actually, I could not uncheck it usually). However, this is required to deploy the site.

It has been over two hours since I choose gh-pages branch as source. So I hold out little hope that it was just a matter of time.

Is there something I forgot to do?

Answer 1

Although my gh-pages branch was fully functional, I needed to push again after I had selected gh-pages branch as the source of my site. It worked.
