Non-standard fonts in SSL?

Question

Fonts

Recently I started to make the site progressdom.ru I installed
the font from the webfonts.ru service and connected the DomainSSL certificate donated free of charge from reg.ru.
Judge the question - why does http display the font, while https remains standard. The first time I encountered an SSL certificate and maybe I missed something

Answer 1

That is, https://www.google.com/fonts/ for example should work? Or maybe someone will tell you where to get a service where there are more Cyrillic fonts
