SOLVED: I can't ping6 my domains. Destination unreachable: Administratively prohibited

Folatt:

Setup

  • Yunohost Server (Xroklaus)
    • Raspberry Pi 3
      • Debian/Yunohost
        • Duniter
      • Domain registered at FreeDNS.afraid.org (guilder-test.eu.org)
  • Desktop computer (MyComputer)
    • ASRock
      • Arch Linux
  • Modem
    • Fritz!Box 7581

I have registered a free domain name called guilder-test.eu.org, which I try to maintain at freedns.afraid.org.

Besides that one, I have another private domain registered at godaddy.com.

Neither are reachable via Ipv6 and I have idea why. I called my ISP and they can't explain it either.


[[email protected] ~]$ ping -6 guilder-test.eu.org
guilder-test.eu.org: Name or service not known

[Update]

It turns out that the IPv6 interface ID is wrong, resolving to ::7664:c1e:6989:14b0 when it should be ::2239:6fcb:6144:21d2. It somehow takes the IPv6 address of the local link, instead of the global one. The question is how to change this as it is automatically generated on my server?
