How To Deploy a Laravel Application with Nginx on Ubuntu 16.04

Hi, I just worked through How To Deploy a Laravel Application with Nginx on Ubuntu 16.04, with SSL and everything, it worked out fine with the quickstart Laravel project from github. Know I wanted to deploy my own project cloned from BitBucket. but I just get a 500 error from the server.

I cloned the bitbucket prooject for the simple sake in the quickstart folder and changed the .env accordingly. Also ```sudo certbot certonly --webroot --webroot-path=/var/www/html/quickstart/public -d mywebdomain.com -d www.mywebdomain.com`` for a new certificate.

Thanks for any help
