Was *all* HTTP-based access deactivated?
I had made the transition to key-based auth for my main project a while ago, then it stopped working about Feb.
The reason I ask, I had a variety of minor projects that were using HTTPS, they continued to work, so I assumed I had done something while learning the keys (like creating an expiry...)
But over time, all the HTTP repositories have failed, and when I went looking in the documentation, they provide instructions only for SSH keys.
