[SOLVE] [emerg] "upstream" directive is not allowed here in /usr/local/etc/nginx/nextcloud.conf:1

Hi,
I try to install nextcloud on a freenas FreeBSD 11.2-STABLE
Nextcloud 14.0.4
I follow this tuto :
http://unflyingobject.com/posts/nextcloud-12-from-scratch-with-freebsd-11/

And when I : nginx -t
I got
nginx: [emerg] “upstream” directive is not allowed here in /usr/local/etc/nginx/nextcloud.conf:1
nginx: configuration file /usr/local/etc/nginx/nginx.conf test failed

My nginx.conf

I read https://docs.nextcloud.com/server/12/admin_manual/installation/nginx.html
but can’t make it.
where should I look for debugging?
thanks for your help

putting the include statement in a http block

[...]
http {
    include       mime.types;
    include nextcloud.conf;
[...]

maybe can solve the problem.
But I got others errors

Any idea why the official docs https://docs.nextcloud.com/server/18/admin_manual/installation/nginx.html do not mention that?

https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/with-nginx-proxy-self-signed-ssl/mariadb/fpm/web/nginx.conf seems more useful than the docs
