Application is generating broken links within the view (stopped working for no reason)

Question

My complete Lumen application suddenly stopped working after one year without problems in the production system (exception on almost any page). As I did not change any code (at least not conciously) I suppose this might be an issue with background changes in the hosting environment.

It all started with a NotFoundHttpException:

(1/1) NotFoundHttpException
in RoutesRequests.php (line 226)
at Application->handleDispatcherResponse(array(0))
in RoutesRequests.php (line 164)
at Application->Laravel\Lumen\Concerns\{closure}()
in RoutesRequests.php (line 413)
at Application->sendThroughPipeline(array(), object(Closure))
in RoutesRequests.php (line 166)
at Application->dispatch(null)
in RoutesRequests.php (line 107)
at Application->run()
in index.php (line 32)

After some research I found a solution to this on SO: NotFoundHttpException with Lumen

It looked like the problem could be solved with putting:

$app->run(
    $app->make('request')
);

into index.php.

However now all of my links within the views are broken - examples:

<link rel="icon" type="image/png" sizes="96x96" href="https://:/images/app/favicon-96x96.png">
<link rel="stylesheet" href="https://:/css/base.css">

The urls are generated in Lumen/src/helpers.php:

/**
 * Generate a url for the application.
 *
 * @param  string  $path
 * @param  mixed   $parameters
 * @param  bool    $secure
 * @return string
 */
function url($path = null, $parameters = [], $secure = null)
{
    return app('url')->to($path, $parameters, $secure);
}

It seems like all parameters are passed correctly: $path is /images/app/apple-icon-57x57.png for instance while the others are empty / null.

Update: After searching for some time I have recognized that:

namespace Symfony\Component\HttpFoundation;

class Request
{
// ...

    /**
     * Gets the scheme and HTTP host.
     *
     * If the URL was called with basic authentication, the user
     * and the password are not added to the generated string.
     *
     * @return string The scheme and HTTP host
     */
    public function getSchemeAndHttpHost()
    {
        return $this->getScheme().'://'.$this->getHttpHost();
    }

// ...
}

... is delivering a wrong scheme (without SSL) and an empty host. But still I do not know why this happens.

After searching for some time I still have no idea where this might come from. Has anybody experienced a similar problem or can help me out on this?

Can you show us your Blade code that's outputting the `` HTML? — ceejayoz, Dec 14 '18 at 16:04
@ceejayoz Lumen appears not to have an `APP_URL` setting (https://github.com/laravel/lumen-framework/issues/595). — Blackbam, Dec 17 '18 at 11:37

After updating from Lumen 5.5 to Lumen 5.7 and updating PHP from 7.0 to 7.2.9 the problem has partly disappeared. Still I had to remove:

    $app->make('request')

The solution from NotFoundHttpException with Lumen did not work in my case and there are still some Exceptions. Better solutions or explanations are still very welcome!
