I believe uncommenting the lines in /etc/nginx/sites-available/default (depending if you have more than one site or not this may not be the desired file you want to alter) that read the following will solve your problem:

Default

server {
        listen 256 default_server;
        listen [::]:256 default_server;

        # SSL configuration
        #
        # listen 443 ssl default_server;
        # listen [::]:443 ssl default_server;
...

Enable listening 443

server {
        listen 256 default_server;
        listen [::]:256 default_server;

        # SSL configuration
        #
        listen 256 ssl default_server;
        listen [::]:256 ssl default_server;
...

If your application auto redirects http to https, great, but incase it helps here's what I have:

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        server_name domain.com;
        return 301 https://$server_name$request_uri;

        # SSL configuration
        #
        listen 443 ssl default_server;
        listen [::]:443 ssl default_server;
...

You should test config and IIRC you need to restart service:

sudo nginx -t
sudo systemctl restart nginx

If you're running a firewall, don't forget to allow ports. More details about your distro will enable me to provide commands.
