https redirection not working correctly

[Parzip]

Hello!

I am trying to set up nginx to 

- switch from http traffic to https
- send alls https traffic to my odoo backend on port 8069

This is already working for different subdomains, but not for the domain
itself. 

http://(www.)subdomain.domain.ch => https://(www.)subdomain.domain.ch
http://(www.)domain.ch => http://(www.)domain.ch, backend ist beeing loaded
but not secured

1) Why is domain.ch not beeing redirected to https://domain.ch?

2) I would like to set up the let's encrypt ssl renewal script described
here:
https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-14-04
For this I need to put a file into the webroot folder, but I don't know how
to define this folder... 

Thank you for your help.


This is my "odoo" file in sites-available:


## odoo backend ##
upstream odoo {
    server 127.0.0.1:8069;

        # force timeouts if the backend dies
        proxy_next_upstream error timeout invalid_header http_500 http_502

        proxy_redirect off;

        # set headers

        proxy_set_header    X-Forwarded-Proto https;
    }

    # cache some static data in memory for 60mins
    location ~* /web/static/ {
        proxy_cache_valid 200 60m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odoo;
    }
}

}
