问题
I am trying to reach my local server via IPv6 which is failing due to certificate issues.
E.g. the nextcloud client gives following error:
$nextcloudcmd --trust --logdebug Nextcloud https://nextcloud.domain.de

Error connecting to server
I wonder why Fritzbox tries to request via .domain.de instead of nextcloud.domain.de.
Can anyone point me into the right direction?

Okay got information from the Site (German: https://avm.de/service/fritzbox/fritzbox-7580/wissensdatenbank/publication/show/3525_Zugriff-auf-HTTPS-Server-im-Heimnetz-nicht-moglich#zd) which led me to following conclusion.
As you do not have NAT for IPv6 addresses and the fritzbox cannot do it as well, the IPv6 has to be from the server. Thus one solution I found is ddclient. By installing it on your GNU\Linux server it will update the IPv6 address at your DynDNS provider. But one thing is still open. I cannot get IPv4 and IPv6 updated.
