How to create a catch all https "default_server" for "Welcome to Nginx!" Page, using self signed certificate in /etc/nginx/conf.d/default.conf

I am running a LEMP server with Nginx, and have the "listen 80 default_server;" directive enabled for port 80 in the catch all /etc/nginx/conf.d/default.conf directive. When I browse to the url: http://my.servers.ip.address , the server automatically redirects to a page that says > Welcome to nginx! If you see this page, the nginx web server is > successfully installed and working. Further configuration is required. > > For online documentation and support please refer to nginx.org. > Commercial support is available at nginx.com. > Thank you for using nginx. However, in my default.conf file, I only have 'default_server' enabled for port 80, because I don't have a https certificate for my servers IP address. So, When I go to https://my.servers.ip.address , instead of Nginx directing me toward a secure version of the default Nginx Welcome page, it directs me to my first valid virtual hosts https address, giving me a > Connection Is Not Private This website may be impersonating > "my.servers.ip.address" to steal your personal of financial > information. you should go back to the previous page. notice first. What I would like Nginx to do is have a "default_server" option in Nginx's default.conf for "listen 443 default_server;" directive, so that when I go to https://my.server.ip.address in a web browser, it goes to a self signed secure version of the default "Welcome to Nginx!" page, instead of one of my virtual host's domains. So my question is, how do I implement a catch all "default_server" in /etc/conf.d/default.conf for https, using self signed certificates, instead of default.conf redirecting to the https address of my first virtual host? Below is my /etc/nginx/default.conf file. server { listen 80 default_server; server_name _; root /var/www/html/; index index.php index.html index.htm index.nginx-debian.html; location / { try_files $uri $uri/ /index.php; } location ~ \.php$ { include snippets/fastcgi-php.conf; } # A long browser cache lifetime can speed up repeat visits to your page location ~* \.(jpg|jpeg|gif|png|webp|svg|woff|woff2|ttf|css|js|ico|xml)$ { access_log off; log_not_found off; expires 360d; } # disable access to hidden files location ~ /\.ht { access_log off; log_not_found off; deny all; } }
