My page at https://ma.thiaso.se/ (alias for https://mathiasose.github.io) has an expired certificate. It has been expired for over 43 hours at the time of writing. Any idea why it hasn’t renewed?
http://ma.thiaso.se/ (without TLS) works fine, and https://mathiasose.github.io redirects there.
As a side-note, I have never been able to select “enforce HTTPS” on the settings page, it has said " Not yet available for your site because the certificate has not finished being issued. Please allow 24 hours for this process to complete." for a long long time now.
