Laravel serve command doesn't read env variables correctly

Question

I have a Laravel 9.5 and there is an issue with the env variables.

In the project root folder, I have .env file and the content is:

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:key=
APP_DEBUG=true
APP_URL=https://liveurl.com

But when I run it with php artisan serve, the env variables are not read correctly.

I have a form

<form action="{{ route('adminlogin') }}" class="text-left" method="post">

but when it's rendered by the serve command, the action is:

<form action="http://localhost/login" class="text-left" method="post">

which is supposed to be https://liveurl.com/login

I have tried to run all the commands to clear cache, route, view, etc. but nothing helps.

php artisan cache:clear
php artisan view:clear
php artisan route:clear
php artisan route:cache

php artisan config:clear
php artisan config:cache
php artisan event:clear
php artisan event:cache
php artisan optimize:clear

php artisan clear-compiled && php artisan optimize

Can anyone help with this issue?

After much time spent digging into the issue, I finally found out the solution is forcing https for all URLs.

There are many approaches introduced, some of them are:

1. Adding FORCE_HTTPS=true in the .env file (which didn't work for me)
2. Adding URL::forceScheme('https') into app\Providers\AppServiceProvider.php file

namespace App\Providers;

use Illuminate\Support\Facades\URL; //--> Need to link this as well
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        URL::forceScheme('https');
    }
}
