You guys can place : LARAVEL_CLOUDFLARE_ENABLED=false before "How it works", where one is updating files, instead of at the bottom. A simple explanation that this plugin won't work on http://127.0.0.1:8000/ because it requires https.

Also had to add:

    use Illuminate\Support\Facades\URL;
    public function boot(): void
    {
        $this->configureDefaults();
        LaravelCloudflare::getProxiesUsing(fn() => CloudflareProxies::load());
        if ($this->app->environment('production')) {
            URL::forceScheme('https');
        }
    }

to app service provider because of console warnings: Mixed Content: The page at '' was loaded over HTTPS, but requested an insecure script ''. This request has been blocked; the content must be served over HTTPS.
