What's the problem 🤔

Wireguard environment based configuration (WIREGUARD_ENDPOINT_IP=2607:9000:9000:13::b47f) with IPv6 works.
Wireguard configuration file (/gluetun/wireguard/wg0.conf) with IPv4 endpoint works.
Wireguard configuration file (/gluetun/wireguard/wg0.conf) with IPv6 endpoint causes error. See log.

(Yes I'm using Mullvad but I wish to use the wireguard configuration file.)

Thanks so much!
