What can I do to fix error 404 page on nginx on Ubuntu 18.04?

I am attempting to switch from apache2 to nginx on Ubuntu 18.04 from the wordpress one click install. I have installed nginx and php-fpm. I did what I thought was a full conversion into nginx using the config files and then uninstalled apache2 but it seems I am missing something… this is my /etc/nginx/sites_available/default.conf, i’m not sure what else is immediately useful so if there is other info needed I can scrounge that up.

server {

        root /var/www/html;
        index index.php index.html index.htm;

        server_name cameingle.com www.cameingle.com;

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

        error_page 404 /404.html;

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
                root /usr/share/nginx/html;
        }

        location ~ \.php$ {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php7.2-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }
