Why does gulp get Cannot GET /css error?

Question

gulp.js

Good afternoon. CSS styles are not applied. In the debug panel, the file is connected.

but when you right-click on the link itself -> open in a new tab, it says this:

The file itself is not empty, but the styles are not applied.

Apparently, something in the connection settings?
Here are the settings:

"use strict";
const { src, dest } = require("gulp");
const gulp = require("gulp");
const autoprefixer = require("gulp-autoprefixer");
const cssbeautify = require("gulp-cssbeautify");
const removeComments = require('gulp-strip-css-comments');
const rename = require("gulp-rename");
const sass = require("gulp-sass");
const cssnano = require("gulp-cssnano");
const rigger = require("gulp-rigger");
const uglify = require("gulp-uglify");
const plumber = require("gulp-plumber");
const imagemin = require("gulp-imagemin");
const del = require("del");
const panini = require("panini");
const browsersync = require("browser-sync").create();

Answer 1

Remove distfrom file path. It should be like this assets/css/styles.min.css
In the browsersync settings, the server folder is specified baseDir: "./dist/", that is, this folder is localhost.
Coming out of this, you are trying to find another dist folder in the dist folder, but it is not there.
