https://status.flathub.org/ is a 404 (even though it's Status OK)

In both Firefox and chromium-browser, the "Flathub Status" page in the footer of most pages on Flathub shows

404

Also, the actual HTTP status returned by the https://status.flathub.org/ page is 200 OK, so sites like IsItDownRightNow and DownForEveryoneOrJustMe report that the page is working and give no useful uptime statistics even though the title and text indicate it is failing. In fact any site URL, e.g. https://status.flathub.org/BOGUSPATH , looks identical while returning status 200 OK
