Laravel route() returning naked IP address instead of domain

Question

Didn't catch this on my local machine but I've noticed some of my pages returning the naked IP address of my web server instead of the domain name. Example:

route('homepage') will sometimes return 192.XX8.X.2XX or 192.XX8.X.2XX/index.php or domain.com/index.php. My pages are cached upon the first visit and there's a rough 50% chance the things will come out weird for all URLs on the page.

Is there an explanation for this weird behavior and how would I fix it? It's quite a concern since Googlebot is listing three additional duplicate copies of my site.

Note: I'm also using the LaravelLocalization package for my routes: https://github.com/mcamara/laravel-localization

I'm also running this app under Laravel Forge (Nginx)

I understand, the question is very old, but I've had same problem and found the solution. (it can help someone)

Open file RouteServiceProvider on this path: app/Providers/RouteServiceProvider.php

Look for function mapWebRoutes. Now we have to add caller domain with config from our environment

protected function mapWebRoutes()
{
    Route::middleware('web')
        ->namespace($this->namespace)
        ->domain(\Config::get('app.url', null))
        ->group(base_path('routes/web.php'));
}

During building the url based on route - system tries to get local variable domain in current route, if it found - the domain should apply immediately. But if property undefined - go to Symfony route module.

PS: Don't forget to set APP_URL in your .env file. Example:

APP_URL=https://mysimpledomain.ua
