It seems that ab encounters some kind of an SSL issue with most https
sites I tried (google, cloudflare proxied sites etc).
Not all, seems to work fine with a personal blog site I host on
Debian/apache2 server or with https://www.debian.org/.
Some kind of an SSL issue but searching around I found nothing, just a
bug from 2013. It's not just my machine, I can repro this in a clean
docker container.
