Custom Wordpress 404 page not loading, Nginx 404 page loading instead.

I’m not sure why, but my custom Wordpress 404 page will not load with an improper URL that should 404, instead, the default Nginx 404 page loads. All pages are working as expected, I just want a 404 to be my 404, not the default. I’ve tried changing my permalinks just to update them, no luck. I suspect it has to do with my sever block, any ideas?

server {
        # The below listen is moved / contained in a server block down below, controlled by CertBot.
        # Only ONE default_server is allowed.
        # listen 80 default_server;
        # listen [::]:80 default_server;

        index index.php index.html index.htm index.nginx-debian.html;

        location / {
            #try_files $uri $uri/ =404;
            try_files $uri $uri/ /index.php?$args =404;
        }

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        }
