Accessing your Home Assistant instance remotely opens up a world of possibilities, from controlling your smart home on the go to receiving real-time notifications. However, ensuring secure remote access is paramount. That’s where Nginx Proxy Manager comes in, providing a user-friendly interface to set up a reverse proxy and secure your connection with SSL/TLS encryption.
Using Nginx Proxy Manager to expose Home Assistant offers several advantages:
- Enhanced Security: The reverse proxy acts as a gateway, shielding your Home Assistant server from direct exposure to the internet and potential threats.
- SSL/TLS Encryption: Nginx Proxy Manager simplifies the process of obtaining and renewing SSL certificates (using Let’s Encrypt), ensuring all communication between your devices and Home Assistant is encrypted.
- Simplified Access: Instead of remembering complex IP addresses and ports, you can access Home Assistant using a memorable domain name.

Troubleshooting Tips
If you encounter issues, double-check the following:
- Port Forwarding: Ensure the correct ports are forwarded from your router to your Home Assistant server.
- Firewall Rules: Verify that your firewall isn’t blocking traffic to the necessary ports.
- DNS Resolution: Make sure your domain name correctly resolves to your Nginx Proxy Manager’s public IP address.
