RRAS VPN Help - Mac Catalina BuiltIn VPN client disconnects after a couple of minutes with activity

Hello fellow r/networking

I have built a RRAS VPN (IKEv2) with PKI authentication for VPN with Windows and Macs, I have gotten it to work partially, I get to connect and get traffic through the tunnel from both kind of OS. But on the mac the client suddenly disconnects from the VPN after a couple of minutes even though there are traffic (PING) going over the tunnel.

ARe there any fellow Network admins taht have ocnfigured this kind of VPN with mac/apple products and if you have had a similar problem.

RRAS Server: Win srv 2019 MAC Client: osX Catalina Authentication: RADIUS/PKI Tunnell Type: IKEv2 (NOT L2TP) 

Thansk in advance for any assistance.
