Hugo theme does not work correctly with netlify

First of all, I have read [this] ([Common Issue] Why isn’t my Hugo theme working correctly with Netlify?) article.
My hugo theme added as submodule and on local machine all seems to be fine.

But with netlify there are some problems with theme.

I just opened your site in Firefox and looked at the console in the developer tools.

Looks like your theme is wanting to pull in some CSS from another URL without using HTTPS.
