Works on http.
Also in the error message:
"What happened?
The origin web server does not have a valid SSL certificate."
Confirmed it works via HTTP though.
Correct, https has some certificate problems, http is still working.
https://getbootstrap.com/dist/css/bootstrap.css is also offline with 526 Invalid SSL Certificate
Argh! I hoped something big was about to happen like: BS4 BETA finally released!
Back up! My apologies, folks.
