CSS breaks down

I connected https, and after that the service broke my css, in some lines added UNUSED

Performing a curl against the origin server on port 443 appears to return the same file. Might check your webserver config.

curl -k --resolve yourdomain:443:[yourip] https://yourdomain/something.css

curl -k --resolve budcapital.kiev.ua:443:[origin IP] https://budcapital.kiev.ua/css/style.css

Do you see the line “UNUSED”?

I do. Replied in your Help Desk ticket as well. I believe an old version of that file is being cached by the nginx server on your local origin server for the https version of the site.
