nslookup api.protonvpn.ch
;; communications error to 127.0.0.1#53: connection refused
我的 nslookup 不适用于所有服务器或 url 我的配置出了什么问题？嗯...我的路由器有问题吗？我不这么认为，自从我买了路由器后，我就没动过设置

我找到了解决方案，结果发现错误出在文件 /etc/resolv.conf 中
我为此安装了几个模块：
sudo apt install openresolv easy-rsa network-manager-openvpn bind9 unbound
之前的内容如下：
#Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
#127.0.0.53 is the systemd-resolved stub resolver.
#run "resolvectl status" to see details about the actual nameservers.
nameserver 127.0.0.1
nameserver 209.222.18.222
nameserver 209.222.18.218
nameserver 192.168.90.1
search itotolink.net
安装后改为：
# This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8).
# Do not edit.
#
# This file might be symlinked as /etc/resolv.conf. If you're looking at
# /etc/resolv.conf and seeing this text, you have followed the symlink.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "resolvectl status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

更换您的 VPN，换一个更好的。您现在使用的 VPN 有垃圾 IP，它们通常都有。获取高级 VPN 或提供专用 IP 的 VPN。只有少数 VPN 提供专用 IP。我一直在使用带有专用 IP 附加组件的 purevpn，刚开始使用一个月，打算只保留一个月，因为它花费很多，但后来我以 88% 的折扣升级了我的 5 年计划。所以，您可能想抓住这个机会，或者只是投资一个您能负担得起的高级 VPN。
