I’ve been using Nginx Proxy Manager for a couple of years now. It provides free SSL with Let’s Encrypt, is designed with security in mind, and is perfect for home networks.

Today, I encountered an issue where Nginx Proxy Manager failed to renew my SSL certificate using Let’s Encrypt. This was actually a problem I faced years ago, but I was too lazy to check the logs.

I hope this helps anyone facing the same issue.

Happy coding! 🚀
