Observed this in the past days and just wanted to create an ticket too.

Yeah, I wish I knew what's causing this...have contacted my web host about it, will see what that leads to. Guess the workaround is to use the http version for now.

The HTTP version also is extremely slow, to the point where it sometimes doesn't load at all.
When I switched my site https://tobireif.com/ to HTTPS using https://tobireif.com/posts/switching_to_https/ it didn't become slow. I hope caniuse.com can be made HTTPs and fast as well ... 馃榾
