CHAP authentication failure on OSX Catalina

I have a user running Mac OS X Catalina 10.15 with all updates. Trying to connect to VyOS via L2TP. Authentication via RADIUS on a Windows Domain Controller.

Running VyOS 1.2.3 stable

The VPN connection works with Windows no problem. The VPN works with older versions of Mac OS X.

In the logs there is a message user CHAP authentication failed.

Has anyone else had this issue? Does anyone know a fix?
