$ cat /etc/nginx/sites-enabled/upstream-45103 
# port 45103, to hc4bookworm.yushei.net:48501 nextCloud

server {
     server_name  munetaka.me:45103;
     charset utf-8;

     location / {
        proxy_pass http://hc4Bookworm.yushei.net:48501;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-Host munetaka.me;
        proxy_set_header X-Forwarded-Port 45103;

     }

     listen 45103 ssl; # managed by Certbot
     ssl_certificate /etc/letsencrypt/live/munetaka.me/fullchain.pem; # managed by Certbot
     ssl_certificate_key /etc/letsencrypt/live/munetaka.me/privkey.pem; # managed by Certbot
}

And https://munetaka.me:45103 will reverse proxy to http://hc4bookworm.yushei.net:48501 nextcloud server, how to set up /var/www/nextcloud/config/config.php???
