WiFi Computer-based authentication not working (WS 2019)

We are trying to do computer-based authentication for our endpoints locally (on-prem AD) and it is not working whatsoever. My CA and NPS are all on one server (WS 2019) and are setup correctly.

- I deployed a certificate template (I duplicated Computer and gave read, enroll, and autoenroll to Desktop Computers)
- I registered NPS with AD.

- I setup RADIUS through my Unifi setup and NPS (including the APs)

- I created a Connection Request Policy that checks to see if it is a wireless connection coming in.

- I created a Network policy for Smart Card or other Certificate ensuring that the CA certificate is selected.

- I created a Wireless policy for my endpoints and selected the CA as the option in the security settings (and as Computer authentication).

When I go to connect to the SSID, it shows the Certificate details for issued to and issued by as the CA server, but it gives an error that it can't connect to the network.
