Hi guix!(service nginx-service-type                            (nginx-configuration                             (server-blocks                              (list (nginx-server-configuration                                     (server-name '("www.example.com"))                                     (root "/srv/http/www.example.com")))))) produce this nginx configuser nginx nginx;pid /var/run/nginx/pid;error_log /var/log/nginx/error.log info;events { }http {    client_body_temp_path /var/run/nginx/client_body_temp;    proxy_temp_path /var/run/nginx/proxy_temp;    fastcgi_temp_path /var/run/nginx/fastcgi_temp;    uwsgi_temp_path /var/run/nginx/uwsgi_temp;    scgi_temp_path /var/run/nginx/scgi_temp;    access_log /var/log/nginx/access.log;    include /gnu/store/dngffa0df8zsxlbi630656688zhly6p5-nginx-1.23.2/share/nginx/conf/mime.types;    server {      listen 80;      listen 443 ssl;      server_name www.example.com ;      root /srv/http/www.example.com;      index index.html ;      server_tokens off;    }}Which will not work because it asks to listen on 443 with ssl, which is not possible because no certificates are provided. Removing the line "listen 443 ssl;" solves this problem.
