How to redirect all https requests to https www subdomain with Nginx?

I have redirects for http to https working fine. But redirects from https to https does not work. Below is my nginx config file. I would think that the if condition would solve things, but it doesn’t. https://example.com gives the error refused to connect when it should redirect to https://www.example.com. How can I fix this? Note, the ssl cert I’m using does support both www.example.com and example.com. I followed the setup from https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04 if that helps.

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

server {
        listen 443 ssl http2 default_server;
        listen [::]:443 ssl http2 default_server;
        include snippets/ssl-example.com.conf;
        include snippets/ssl-params.conf;

        root /var/www/html;

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

        server_name _;
       	 if ($host = "example.com") {
	 	return 301 https://www.example.com$request_uri;
	 }

        add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

        location ~ /.well-known {
                allow all;
        }

        location / {
                try_files $uri $uri/ =404;
        }
}

Remove:

if ($host = "example.com") {
    return 301 https://www.example.com$request_uri;
}

Change:

server_name _;

To:

server_name example.com www.example.com;

Then restart NGINX and let me know if that works.

You can use this inside of the server directive.

if ($scheme = http) { rewrite ^/(.*)$ https://example.com/$1 permanent; }

you can also try following.

server {

       listen [::]:80 default_server;
       server_name example.com www.example.com;
       return 301 https://www.$server_name$request_uri;
}

server {
        listen 443 ssl http2 default_server;
        listen [::]:443 ssl http2 default_server;
        include snippets/ssl-example.com.conf;
        include snippets/ssl-params.conf;

        root /var/www/html;

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

        server_name example.com www.example.com;

        add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

        location ~ /.well-known {
                allow all;
