Docker compose configuration returning 404

[ddelizia]

I'm trying to deploy a prestashop container and want to add https + letsencrypt using the container you built.

i copied the nginx.tmpl from https://github.com/fatk/docker-letsencrypt-nginx-proxy-companion-examples/blob/master/volumes/proxy/templates/nginx-compose-v2.tmpl and

I followed instruction from your example https://github.com/fatk/docker-letsencrypt-nginx-proxy-companion-examples/blob/master/docker-compose/v2/simple-site/docker-compose.yml but I get default nginx page (no prestashop is accessible). If I try mysite.com:8090 I can successfully access prestashop instance.
Here I copied some log from console:

nginx                             | 2016/04/09 12:02:26 [emerg] 1#1: no host in upstream ":80" in /etc/nginx/conf.d/default.conf:35

Like said in the REAME of the example site: https://github.com/fatk/docker-letsencrypt-nginx-proxy-companion-examples#docker-compose-v2 you need an unofficial version of nginx.tmpl to use version 2 of docker-compose.
