I'm setting up a site for myself using nginx and letsencrypt, and I wanted to set up HSTS preloading for the added security benefits, however when I check the url with multiple different scanners, HSTS headers are not sent.
Here's the relevant block in server config:
server {
root /var/www/html/pyroballpcbs;
index index.php index.html index.htm;
server_name pyroballpcbs.com www.pyroballpcbs.com;
server_tokens off;
client_max_body_size 20M;
location / {
#try_files $uri $uri/ =404;
try_files $uri $uri/ /index.php$is_args$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}
location = /favicon.ico { log_not_found off; access_log off; }
location = /robots.txt { log_not_found off; access_log off; allow all; }
location ~ /\.ht {
deny all;
}
location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
expires max;
log_not_found off;
}

}
server {
if ($host = www.pyroballpcbs.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = pyroballpcbs.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
#listen [::]:80;
add_header Strict-Transort-Security "max-age=63072000; includeSubdomains" always;
server_name 10.1.10.15 pyroballpcbs.com www.pyroballpcbs.com;
return 301 https://$host$request_uri; # managed by Certbot
}
Here's output from an nmap script designed to check security headers:
$ nmap -p 443 --script http-security-headers pyroballpcbs.com

hstspreload.org is also showing the same issue, as well as ssllabs.com's scanner:

and nginx service status output:
