nginx subdomain with different site than root - nginx

Question

I have the following configuration in my sites-available (with a symbolic link to enable):
#subdomain site
server {
listen 443 ssl http2;
server_name dokuwiki.[censored].org;
root /var/www/html/dokuwiki;
index index.php index.html;
include /etc/nginx/templates/ssl.tmpl;
location / {
try_files $uri $uri/ #dokuwiki;
}
location #dokuwiki {
rewrite ^/_media/(.*) /lib/exe/fetch.php?media=$1 last;
rewrite ^/_detail/(.*) /lib/exe/detail.php?media=$1 last;
rewrite ^/_export/([^/]+)/(.*) /doku.php?do=export_$1&id=$2 last;
rewrite ^/(.*) /doku.php?id=$1&$args last;
}
location ~ \.php$ {
# Caution: be sure the php7.2-fpm.sock matches your version
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /(data|conf|bin|inc|vendor)/ {
deny all;
}
}
I want to have a different site at the site root:
#root site
server {
listen 80;
server_name [censored].org;
root /var/www/html/site;
index index.html;
}
The root site is just a dummy for now. When I try to load it, the browser tries to load the subdomain site, but issues a warning because the ssl certificate (which is set up for the subdomain) doesn't match.
Clearly I'm doing something wrong, but what?

Try scaling back to a minimal configuration without SSL and ensure things work for 2 domains first:
server {
listen 80;
server_name example.com;
return 200 "example.com";
}
server {
listen 80;
server_name 1.example.com;
return 200 "1.example.com";
}
$ curl http://example.com/
example.com
$ curl http://1.example.com/
1.example.com
Then, add SSL to an HTTPs endpoint to ensure that works:
server {
listen 443 ssl http2;
ssl_certificate example.com.crt;
ssl_certificate_key example.com.key;
server_name example.com;
return 200 "example.com";
}
$ curl https://example.com/
example.com
