服务器拒绝请求，原因是来自Fritzbox的域错误

Question

我试图通过IPv6访问本地服务器，该服务器由于证书问题而失败。

例如，nextcloud客户端提供了以下错误：

$nextcloudcmd --trust --logdebug Nextcloud https://nextcloud.domain.de

我想知道为什么Fritzbox尝试通过.domain.de而不是nextcloud.domain.de请求。

有人能把我引向正确的方向吗？

好的从网站(德语：https://avm.de/service/fritzbox/fritzbox-7580/wissensdatenbank/publication/show/3525_Zugriff-auf-HTTPS-Server-im-Heimnetz-nicht-moglich#zd)获得信息，这让我得出了以下结论。

由于IPv6地址没有NAT，而fritzbox也不能这样做，所以IPv6必须来自服务器。因此，我找到的一个解决方案是ddclient。通过在您的GNU服务器上安装它，它将更新您的IPv6提供者的DynDNS地址。但有一件事还没有解决。我无法更新IPv4和IPv6。
