Why is css not loading after joomla domain transfer?

Question

css

Moved Joomlu to a subdomain. Styles (css) stopped loading. Although when viewing the "page code", the paths are correct.
In the "config" corrected the values.
There are no errors in the "Debugger" mode.
The site itself works, but without registration. The admin panel is also fully functional, but without registration. As if css is not used at all.
Tell me where to dig. Is it possible that the template has fallen off? Even though I checked everything.
UPD: Many pictures are no longer displayed. But when you go to the image, open. They are in the directories, but perhaps due to the fact that the paths to them are also specified in css, they do not open. The third day I'm breaking my head.
In console: Resource interpreted as Stylesheet but transferred with MIME type text/html

Answer 1

The problem is in the processing of files by the web server.
You need to look at the server config.

Answer 2

He tells you in Russian English that the files are given with the wrong MIME type. Those. the browser sees that the given content is like CSS, and the server says that it is serving HTML. Probably therefore styles also are not applied.
