Wireguard – вопрос по первоначальной настройке

Я следовал этому руководству: https://www.digitalocean.com/community/tutorials/how-to-set-up-wireguard-on-ubuntu-20-04 .

Я дошел до конца и теперь пытаюсь запустить службу Wireguard.

Я надеюсь, что кто-нибудь сможет заметить очевидную ошибку, которую не замечаю я сам, или направит меня в правильном направлении. Заранее большое спасибо.

Мой wg0.conf выглядит так:
