Would like to run laravel app on ec2 - url not responding

i would like to run my laravel app on production.

For installion I did the following documentation: https://www.rosehosting.com/blog/install-laravel-on-ubuntu-16-04/

I also added write premissions for /storage and /bootrap/cache

But if I open my domain nothing response HTTP ERROR 500

My side-config looks like this:

<VirtualHost *:80>
ServerAdmin admin@localhost
DocumentRoot /var/www/html/test/public/
ServerName localhost
ServerAlias localhost
<Directory /var/www/html/test/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/your_domain.com-error_log
CustomLog /var/log/apache2/your_domain.com-access_log common
</VirtualHost>

Any idea what I did wrong or how I can debug this?
