HTTPS not available - mig.mozilla.org

The issue here isn't that there isn't HTTPS, but that the certificate used for the site is signed for GitHub. Since no subjectAltName extension values are provided, the Common Name is the source of truth that the browser relies on.

You may also want to look at the TLS analysis section of the Observatory. The certificate itself is valid. https://observatory.mozilla.org/analyze.html?host=mig.mozilla.org#tls

I'd suggest the maintainers update the certificate, but otherwise this issue should be closed.
