Can't clone public repository using https://

I just made a repository public when it had been private, previously. I can clone this fine (in Git Bash) using git://, but I can’t clone using https:// and I want to use ReadTheDocs which requires a valid https:// or git:// url. ReadTheDocs claims that the https:// url doesn’t work and neither does the git:// url. I can confirm that I can’t browse the source in the browser at So, it seems like it’s not public via https:// but is public via ssh://.

Any help?
