Site redirected you too many times.

I created a Wordpress site following up this tutorial - https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-with-lemp-on-ubuntu-18-04, haven’t configured ufw firewall, skipped that part

After installing SSL, I’m getting “syscodes.io redirected you too many times” error…

Here is the server block file below

server {
        root /var/www/html;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name syscodes.io www.syscodes.io;

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

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        }

        location ~ /\.ht {
                deny all;
        }
           location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt { log_not_found off; access_log off; allow all; }
    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }

    listen 443 ssl; # managed by Certbot

}
server {
    if ($host = www.syscodes.io) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = syscodes.io) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen 80;
        server_name syscodes.io www.syscodes.io;
    return 404; # managed by Certbot




}
