Use nginx-proxy and wordpress in docker - wordpress

Question

I try to host some wordpress with an nginx proxy above:
This is my docker-compose.yml
proxy:
image: jwilder/nginx-proxy:0.4.0
ports:
- "80:80"
- "443:443"
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
# SSL Certificates
- /etc/letsencrypt/live/mysupersite.com/cert.pem:/etc/nginx/certs/site.com.crt:ro
- /etc/letsencrypt/live/mysupersite.com/privkey.pem:/etc/nginx/certs/site.com.key:ro
wordpress:
image: wordpress:4.8.1-php5.6-apache
expose:
- 80
volumes:
- /var/www/html:/var/www/html
restart: always
environment:
- WORDPRESS_DB_HOST=mysql
- WORDPRESS_DB_USER=dev
- WORDPRESS_DB_PASSWORD=passwd
- WORDPRESS_DB_NAME=db
- VIRTUAL_HOST=mysupersite.com,www.mysupersite.com
Everything seems to start well. I have 2 running containers.
But I'm not able to visit my website on https://mysupersite.com in my browser.
What part am I missing? Do I need extra configuration somewhere?
I see this error in my browser:
The page isn’t redirecting properly
