The installation script handles everything needed to get Nginx Proxy Manager up and running:

Default login credentials:

• Email: admin@example.com
• Password: changeme

Important: Change your password immediately upon first login!

If you encounter any issues:

1. Check the logs with: sudo journalctl -u npm -f
2. Ensure all required ports (80, 81, 443) are open and not used by other services
3. Verify that the system has sufficient resources (RAM, CPU, storage)

Common solutions:

• Restart the services: sudo systemctl restart openresty npm
• Check firewall settings: sudo ufw status

After installation, consider:

1. Securing the admin interface by restricting IP access
2. Setting up HTTPS for the admin interface
3. Using strong passwords and regular updates
4. Setting up a firewall (UFW) to restrict access
