Security & setup warning, seems like these were addressed

🚧 Installation
1

I just installed NC17 on Debian Buster with nginx

In the Settings|Administration|Overview I see Security & setup warnings as below:

NextcloudWarnings
NextcloudWarnings1317×352 39.6 KB

In my /etc/nginx/sites-available/nextcloud file I have:

# Add headers to serve security related headers
add_header Strict-Transport-Security "max-age=15768000; includeSubDomains; preload;";
add_header X-Content-Type-Options nosniff;
add_header X-Frame-Options "SAMEORIGIN";
add_header X-XSS-Protection "1; mode=block";
add_header X-Robots-Tag none;
add_header X-Download-Options noopen;
add_header X-Permitted-Cross-Domain-Policies none;

So it appears they are all addressed except “Referrer-Policy”. Do I need to put these elsewhere or add sometype of override? Would “Referrer-Policy” be set in the same place? Any help would be appreciated.

Thanks,
Dennis
