I don’t know why this is happening. I have more than thirty repositories within an organization. They are all served fine on http and https but one. Internally, their settings are the same, but this one repository is being served over
http://<org>.github.io/<repository-name> but not
https://<org>.github.io/<repository-name> (on https I get a 404 error).
What could possibly cause this? Something in the files being served?
