Can I Use Let's Encrypt Certificates with a Network Policy Server?
Asked by
TechieWizard42
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.

CertGuru88: 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.
