I’ve contacted Richard Hicks about this, appears to be IKEv2 Fragmention, this solution works https://directaccess.richardhicks.com/2019/02/11/always-on-vpn-and-ikev2-fragmentation/

TLS-support would be a significant improvement for this young product, hope Microsoft will add this.

Hello Joseph

Interesting article, thanks for that!

Have you tried the device tunnel over the Internet? I have a fully functional AlwaysOn VPN in lab. The User Tunnel dials in perfectly over the Internet, but the Device Tunnel keeps on failing. Error 809, indicating connectivity problems, but since the User Tunnel works over the same IKEv2 we can rule that out. Device Tunnel does connect on premise.
