I just get a blank white page, viewing from UK. This might have something to do with the fact that the web page doesn't actually have any content in the HTML file, and even if it did, the CSS file has "display: block" so one wouldn't be able to see it.
Same from USA (Massachusetts). Also got a "Not Secure" warning from Chrome. I assume it's the hug'o'death.
The certificate served to me was valid until December 2022
Same, but Chrome still didn't want to show the page and said the date was invalid...
