Laravel Sail Docker MySQL not connecting

I am trying to access a database through an laravel app that is being deployed through a docker container but for some reason I get the following message:

SQLSTATE[HY000] [2002] Connection refused
SELECT * FROM `posts`

The database has a table named posts and I'm trying to access from localhost/posts.

The blade template for /posts is the following:

@extends('app')
@section('content')
    <h1>Posts index page</h1>
    @forelse ($posts as $post)
        <h2>{{ $post->title }}</h2>
    @empty
        <h2>No posts!</h2>
    @endforelse
@endsection

The Route in web.php responsible for /posts is this one:

Route::resource('/posts', PostController::class)->only(['index', 'store']);

And the index function of the PostController is this one:

public function index()
    {
        $posts = Post::all();
        return view('posts.index', compact('posts'));
    }

My .env file looks like this:

My operating system is Windows 11 and I'm running MySQL Workbench on it. That is why I am exposing 3307 port instead of 3306.

With the current setup I can run php artisan migrate without a problem from wsl terminal.

What can I do in order to access posts from localhost/posts without getting Connection refused error?

SOLUTION Solved it by changing DB_HOST=mysql in .env but also the DB_PORT to 3306.

EDITED .env

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=laravel_essentials_app
DB_USERNAME=sail
DB_PASSWORD=password
