Just in case someone lands here for Laravel 11, where the TrustProxies.php file does not exist anymore, you can achieve @hermeneus proxy fix into bootstrap/app.php :

return Application::configure(basePath: dirname(__DIR__))
    // Your code…
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->trustProxies(headers: Request::HEADER_X_FORWARDED_FOR |
            Request::HEADER_X_FORWARDED_HOST |
            Request::HEADER_X_FORWARDED_PORT |
            Request::HEADER_X_FORWARDED_PROTO |
            Request::HEADER_X_FORWARDED_AWS_ELB
        );
        $middleware->trustProxies(at: '*');
       // Rest of your code… ```
