L2TP over IPSec PSK from Windows 10 Client

Hi,

i currently have an Issue with Windows 10 clients connecting to ROS 6.38.4.

The Setup works with iOS Clients but Windows clients hang while connecting.

The ROS debug logs show no errors. For me it looks like phase 2 is established
but the handshake does not proceede to l2tp.

The last message of the debug log are in the screenshot attached.



Does anybody else experience this issue?

Regards
Ekkehard
