Не удается подключиться к IPsec / L2TP в OpenSUSE Tumbleweed

Я хочу получить доступ к сети VPN с моего ноутбука, на котором работает OpenSUSE Tumbleweed. Проблема в том, что я не могу подключиться ни к NetworkManager, ни к настройке чего-либо вручную.

РЕДАКТИРОВАТЬ: Проблема не на стороне сервера, так как я могу подключиться к VPN с помощью устройств Windows, Android и Ubuntu.
