404 - File Not Found

Hi all,
I'm running the ci_news app on my local network:

Code:

php spark serve --host 192.168.1.15

CodeIgniter CLI Tool - Version 4.0.4 - Server-Time: 2020-11-03 09:21:28am
CodeIgniter development server started on http://192.168.1.15:8080

I can load the default page into a browser:

http://192.168.1.15:8080/
Welcome to CodeIgniter 4.0.4

But after going through the tutorial I cannot  load the pages.

It's throwing the exception called from Controllers/Pages.php:
throw new \CodeIgniter\Exceptions\PageNotFoundException("hmm.. not found: ". $page);

Do you have any advice?
thank you.
