@sahandMg Hello! L2TP kernel support not detected means your Docker host does not have IPsec/L2TP kernel support, see [1] for more info. This message can be safely ignored and does not affect the VPN functionality. You may troubleshoot further by enabling the Libreswan (IPsec) logs [2]. If no new logs appear after attempting to connect, then traffic did not reach your VPN server.
