It was working fine for months, but after trying to set a new RSS feed, all styles were broken
Raspberry is embedded in my smart door, so I need to tear the door apart to reach it

Is there any way to either create this file remotely or set config to bypass it?
All other functions work as usual, not sure what’s even the root of problem
Also found that all HTML elements (regions) have display: none; active

Refused to apply style from 'http://192.168.68.109:8080/css/custom.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
