Switch to IKEv2 without L2TP. It will be much better and saves you like PPP plus L2TP encapsulation layers. And you won't need xl2tpd anymore.

Could you please tell more about how to switch to IKEv2 without L2TP

I set up vpn using this guide https://github.com/hwdsl2/setup-ipsec-vpn/blob/master/docs/ikev2-howto.md#configure-ikev2-vpn-clients

@KornyAS Hello! The "Fatal signal 15 received" message is normal, it is usually logged when the xl2tpd service restarts. From your comments, it looks like you are already using IKEv2 mode. xl2tpd is not used in this mode.

The issue you described could be caused by multiple devices sharing the same IKEv2 certificate. To fix, make sure that you create a unique IKEv2 certificate for each device. See Manage IKEv2 clients for more details.

I just created the new certificate for my pc - connected it and in less than 10 minutes - I recieved No internet. How can it be possible?
