Why does the subfolder take styles from the main site? How to change it?

Question

Nginx

Hello everyone, I ran into such a problem: there is a site x.com. Documentation has appeared that is not located in the folder of the main site and is not attached to them in any way except for the domain (/var/www/x vs /var/www/docs). I set up a subdirectory, goes to x/docs.com, but takes all styles, pictures, etc. not in the docs folder, but in x .
What I did:
- specified the root folder in ^~ /docs
- put try_files, etc.
If you make a subdomain (docs.x.com), then everything works as it should. What do you advise? What to push off?
