How can I add SSL certificate?

How can I add a ssl certificate to get the login page for first time?

Working for my demo : Nginx as reverse proxy with a Let's Encrypt certificate (using certbot). But public ip will not be logged by Nexphisher (will only see127.0.0.1) : must refer to nginx access.log file.

nginx conf file :

server {
   listen 443;
   server_name XXXXXXXXXX.YYY;
   ssl on;
    ssl_certificate /etc/letsencrypt/live/XXXXXXXXXX.YYY/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/XXXXXXXXXX.YYY/privkey.pem; # managed by Certbot
   ssl_protocols TLSv1.2 TLSv1.3;
 ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA HIGH !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";
   ssl_prefer_server_ciphers on;
     location / {
     limit_except GET HEAD POST { deny all; }

   proxy_pass http://127.0.0.1:5555;
   }

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