We have just checked your site and see Golos Text font already changed in code: https://prnt.sc/0vHdtRHalXaW
However the font on the site doesn’t change, it means you haven’t loaded this font in Appearance -> Custom Fonts (or font files wrong)
These fonts you are using already have in Google Fonts and you don’t need to use custom fonts in this case.
You can deactivate Custom Fonts plugin then select Font load from Google Fonts.
Now it’s working fine on your site.
Hope this helps!
