Hey, I’m somewhat new to Docker. I’ve installed Vaultwarden on an Ubuntu server VM with IPv6 only. Everything works fine in principle, but the admin UI tells me “Internet access error” and it doesn’t generate the little website images for the individual passwords. How do I set it up so that it can basically pull everything via IPv6? I would be very grateful for a quick guide!
