I think I am missing something simple, but I just can't see it.
I am running the latest Nginx on a home machine running Ubuntu 20.04 version 2. I have pfsense as my router/firewall running on a different machine. I have setup a DDNS ([my_name].ddns.net) entry to point to my ever changing WAN IP address.
I have a domain name "[my_name].net". I have been able to create a Let's Encrypt certificate for both domains on my Ubuntu/Nginx machine: [my_name].net and [my_name].ddns.net.
I created a CNAME record mapping "www" to "[my_name].ddns.net" on the site that hosts my domain.
When I access https://[my_name].ddns.net, the website comes up perfectly.
When I access https://www.[my_name].net, the website comes up with a certificate warning because it is pulling the certificate for https://[my_name].ddns.net.
The nginx configuration for the www.[my_name].net website is:
server {
listen 80;
root /var/www/html;
index index.html
server_name www.[my_name].net;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}
}
server {
root /var/www/html;
index index.html
server_name www.[my_name].net;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/www.[my_name].net/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/www.[my_name].net/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}
What do I have to do to get Nginx to "see" the redirected URL as www.[my_name].net and not [my_name].ddns.net?
Thanks a bunch.
