I have looked over just about every article I can find on this. I am trying to get NPS/Radius Server to authenticate against the Azure Point to Site VPN.

The NPS/Radius Server is 1 of 3 VMS inside our Azure Subscription. The Server is a 2019 data center box running ADDS, DNS, NPS/RADIUS. With an IP of 172.10.20.4

Main Virtual Network Subnets:

Supernet: 172.10.0.0/16

AzureFirewallSubnet: 172.10.10.0/24

SVR: 172.10.20.0/24 (Where all of our cloud servers are running, with static IPS)

MerakiVMXSubnet: 172.10.50.0/24 (This subnet is for VMX100 VPN Concentrator, traffic is flowing just fine on this subnet to our on-prem Meraki)

GatewaySubnet: 172.10.0.0/24

Note: The DNS on the Virtual Network is set to 172.10.20.4 and 172.10.20.5 which is the two AD, DNS servers in the SVR subnet.

Virtual Network Gateway

Address Pool: 192.168.100.0/22

Tunnel Type: IKEv2 and SSTP (SSL)

Radius (Enabled) ServerIP: 172.10.20.4

SharedSecret: Same on NPS and Azure

I hope I am missing something simple. I have also attached a screenshot of the radius server configuration. I have also confirmed that the account I am trying to access with is eligible to make the connection.
