Anyone else seeing "net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH"? Happens both in Firefox mobile and another browser that's a thin wrapper around Google's Chromium Webview. I'm surprised nobody mentioned it yet if firefox and chromium both struggle with this site. Or do they use a common TLS engine on Android?
Sadly http is not supported, it forces https for what I understand (from the title) to be a little web toy
Edit: same issue on Firefox desktop on Linux. It gets the redirect from github.io and then a ciphersuite mismatch. I now guess the host got some faulty update and it's not a me issue
