Welcome to nginx! after droplet backup restore (emergency)

My client has paid ads and visitors coming to their site and they’re going crazy, so I’m a little frustrated here.

http://www.signa.com

After restoring a droplet from when the site worked, I’m getting “Welcome to nginx!”

Following the instructions in this discussion: https://www.digitalocean.com/community/questions/website-only-show-welcome-to-nginx

I’m getting a 403 error

Nothing in: /var/log/nginx/error.log.1 /var/log/nginx/error.log

Inside /etc/nginx/sites-available/default (comments removed):

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        root /var/www/;
        index index.html index.htm;

        server_name localhost;

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


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

— update as I’m troubleshooting —

I used this tutorial to set up my droplet with wordpress: https://www.digitalocean.com/community/tutorials/how-to-migrate-wordpress-from-shared-hosting-to-a-cloud-server-with-zero-downtime

I didn’t install nginx, I installed Apache. I’m not sure why it was running.

I’ve stoped nginx and restarted apache but I’m getting an error: /etc/init.d/apache2 restart

• Restarting web server apache2 [fail]
• The apache2 configtest failed. Output of config test was: AH00526: Syntax error on line 33 of /etc/apache2/sites-enabled/default-ssl.conf: SSLCertificateFile: file ‘/etc/letsencrypt/live/www.signa.com/cert.pem’ does not exist or is empty Action ‘configtest’ failed. The Apache error log may have more information.

/etc/letsencrypt/live/www.signa.com/cert.pem is not empty, there is a certificate inside I’ve just verified

Apache error logs (/var/log/apache2/error.log) only have logs from Yesterday, nothing from today
