@SOmeONee

You can apply workaround from development version of xl2tpd as follows:

first, run this on your host (given your container is running):

docker exec -it ipsec-vpn-server bash

then inside a container:

apt-get install -y build-essential git libpcap0.8-dev
git clone -b 1.3.12 https://github.com/xelerance/xl2tpd.git
cd xl2tpd
make
cp xl2tpd /usr/sbin/xl2tpd
service xl2tpd restart

Then container restarts and you'll be able to connect (at least it's working for me, Ubuntu 18.04 on Digitalocean + L2TP/IPsec router client)

This is dirty workaround since it downloads a lot of packages for your container, but at least it works and may be an option for you.

Originally dev version installation instructions are posted here

Dirty workaround but that will make it until image gets an update.
Thanks @sharipov-ru !
