Xbox 1 S won't connect.

I have run through the entire troubleshooting page here, yet come up with nothing.

The strange thing is, I have a PS4 Pro on the same network, and it will connect just fine.

I have tried disabling antivirus and firewall, I have updated my server to the latest version, tired logging in an out on both the server and the app. Yet the Xbox 1 will not connect.
