设置中的"VPN DNS"影响使用 #4049

Open slovx2 opened 6 days ago

slovx2 commented 6 days ago

想了解一下设置中的"VPN DNS"具体作用是什么。 我有部署了两台服务器，都是用x-ui部署的ss协议，一台在bandwagon-美国，一台在华为-香港。 这两个节点在其他平台客户端上使用都正常（iOS V2Box、Mac V2RayU、 Win V2RayN）。 唯独在Android的此app上使用有问题。

预期行为

VPN DNS 默认设置下都能正常访问

实际行为

  1. VPN DNS 设置为 “1.1.1.1” 时，美国节点可正常使用；清空VPN DNS设置时，美国节点无法正常使用
  2. VPN DNS 设置为 “1.1.1.1” 时，香港节点无法正常使用；清空VPN DNS设置时，香港节点可正常使用。

所谓“无法正常使用”指的都是包括C浏览器在内所有APP无法访问国内和国外网络，（Chrome提示： DNS_PROBE_FINISHED_NO_INTERNET）

复现方法

如上所述，我可以提供服务器信息以供测试，但我不确定在别的手机上能不能复现。 这导致我在两个节点间切换时，总要修改VPN DNS 设置

日志信息

以下是 2. VPN DNS 设置为 “1.1.1.1” 时，香港节点无法正常使用；时的日志
