我正在尝试通过IPv6访问本地服务器，由于证书问题，该服务器失败。
例如nextcloud客户端给出以下错误：

我不知道为什么Fritzbox尝试通过.domain.de而不是nextcloud.domain.de进行请求。
有人能指出我正确的方向吗？
好的，您从站点上获得了信息（德语：https://avm.de/service/fritzbox/fritzbox-7580/wissensdatenbank/publication/show/3525_Zugriff-auf-HTTPS-Server-im-Heimnetz-nicht-moglich#zd），这使我得出以下结论。
由于您没有用于IPv6地址的NAT，并且fritzbox也无法做到这一点，因此IPv6必须来自服务器。因此，我找到的一种解决方案是ddclient。通过将其安装在GNU \ Linux服务器上，它将在DynDNS提供程序处更新IPv6地址。但是有一件事仍然是未解决的。我无法更新IPv4和IPv6。
