For some website that are actually only served by https, but have really slow servers, Chromium is just impossible to visit them.
After only a few seconds, it will show a page like "You are seeing this warning because this site does not support HTTPS."
I can either refresh the page and it will just timeout again; or choose to enter the http version, which is either an error page, or just not exist.
On Firefox those sites works fine.
