Как настроить редирект с http на https и с www на no-www?

#redirect

server {
    listen              80;
    server_name "~^(www\.)?(.*)$" ;
    return 301 https://$2$request_uri ;
}


#В этом блоке пытался оставлять строки с ssl и закомментированными и раскоментированными 
server {
        listen 443 ssl;
        server_name "~^www\.(.*)$" ;
        return 301 https://$1$request_uri;
        #ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
        #ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
        #include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        #ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
        #listen [::]:443 ssl ipv6only=on; # managed by Certbot
        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

        #root directory
        root /var/www/example.com/public;
        #domain name
        server_name example.com;
        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm;
