nginx reads the config from /etc/nginx/sites-enabled/
usually there are just links from /etc/nginx/sites-available.

when generating certificates with certbot, choose 'webroot' option if there is a directory that is served. 
Cerbot will place the test files there - and will ask the disk location where the exposed dir is located like '/var/www'


certbot generates certificates in /etc/letsencrypt/live/balamaci.eu/
and you need to reference them in nginx site config:
