What is mine, in connecting fonts?

Question

Fonts

I connect the Lato font (with Cyrillic support) to my project. But it seems that he does not pick up the Cyrillic alphabet. The difference between Latin and Cyrillic characters is very visible. Tell me please, what could be the problem?

Answer 1

I don't see lato-bold in connecting fonts. Apparently the browser cannot render it at all and connects a different font.
