I'm wondering if anyone has successfully utilized a Let's Encrypt certificate for their Network Policy Server (NPS). From what I've gathered, Let's Encrypt typically doesn't issue certificates for internal resources — has anyone found a workaround for this? I want to set it up for my home WiFi as a proof of concept for work. For context, I'm using a UDMPro and a UniFi AP 7 Access Point that I plan to connect to a Server 2025 Domain Controller.

Yeah, you can definitely use Let's Encrypt certificates for NPS! The misconception that they only issue certs for public domains is not entirely accurate; they do allow for HTTP validation, which opens up possibilities. Just keep in mind you need to own the domain you're requesting the cert for.
True, but if you're trying to use it for something like 'home.local', you might run into issues since that's not a public domain.
