Dompdf not working in production

Hi folks - A bit off-topic here. I'm using Barryvdh/DomPDF to produce user pdfs. Everything is working in my local environment, with one odd issue, but in production (DigitalOcean) nothing seems to be happening when I click the link and no error messages are being logged.

The controller:

use Barryvdh\DomPDF\Facade as PDF;
public function pdf()
{
... Create variables...
$invoice = PDF::loadView('registrants.pdfs.invoice',
            [
                'balance' => $balance,
                'due' => $due,
                'event' => Event::getCurrentEvent(),
                'paid' => $paid,
                'registrationfee' => $registrationfee,
                'readingsessions' => $readingsessions,
                'readingsessionsfee' => $readingsessionsfee,

            ])
            ->setPaper('letter','portrait');

        return $invoice->download('MySummerConferenceInvoice.pdf');
}
The one odd issue is the PDF in PDF::loadView is struck-through (i.e. it has a line through it).  I'm using PHPStorm as my IDE, but I haven't figured out what the IDE is trying to tell me.
In production, I've done a "php artisan optimize" and "composer update", so I think I'm all-good there.
Any thoughts or suggestions are appreciated!
Best - Rick

@sinnbeck Thanks for the response! I checked and all of the requirements are being met. However, In case this helps someone else, the solution to the problem is in the app/Http/Middleware/TrustProxies.php file. I discovered this in solving a bigger problem of my routes not working in production (going to http rather than https domain). Solving this problem by changing the

/**
     * The trusted proxies for this application.
     *
     * @var array|string|null
     */
    protected $proxies;

/**
     * The trusted proxies for this application.
     *
     * @var array|string|null
     */
    protected $proxies = "*";

solved both problems!
