Here's what I know so far... This breaks my websites SSL on Opera and Chrome on my late `09 Mac Mini, and Chrome on a new Raspberry Pi 4, and Safari on my old iPhone 5s.<p>Even the <a href="https://community.letsencrypt.org/" rel="nofollow">https://community.letsencrypt.org/</a> site is broke in those.<p>On all of those devices my sites work fine in Firefox. I have to think this is biting more folks than we know right now. I mean, I know my Apple stuff is old, but there's still a lot of old hardware out there.
