After deployment, I changed my project folder name from /var/www/html to /var/www/stand_blog and now I have View Not Found error in browser

So I deployed laravel app using lemp nginx droplet. It was working fine. I changed the project folder name from /var/www/html to /var/www/stand_blog and I ediied digitalocean file in /etc/nginx/sites-available so that the root points to /var/www/stand_blog/public. I restarted nginx using sudo systemctl restart nginx and it said time out error. I waited for around 15 minutes and tried again and it was restarted successfully. I checked sudo nginx -t and it says ok. But when I check the browser, I got view not found error. Is there anything I need to do? Thank you.
