提交 Issue 之前请先阅读 Issue 指引，然后回答下面的问题，谢谢。
除非特殊情况，请完整填写所有问题。不按模板发的 issue 将直接被关闭。
如果你遇到的问题不是 V2Ray 的 bug，比如你不清楚要如何配置，请使用Discussion进行讨论。

你正在使用哪个版本的 V2Ray？（如果服务器和客户端使用了不同版本，请注明）
4.22.1 服务器与客户端版本一致
你的使用场景是什么？比如使用 Chrome 通过 Socks/VMess 代理观看 YouTube 视频。
v2rayN, 网页和YouTube
你看到的不正常的现象是什么？（请描述具体现象，比如访问超时，TLS 证书错误等）
域名解析问题, 浏览器包ERR_CONNECTION_CLOSED, 检查日志后发现报错如下

2020/02/28 03:47:43 [Warning] v2ray.com/core/app/router: resolve ip for flick > v2ray.com/core/app/dns: invalid domain name
2020/02/28 03:47:43 [Warning] [1070997716] v2ray.com/core/proxy/freedom: failed to get IP address for domain flick > v2ray.com/core/app/dns: invalid domain name

你期待看到的正确表现是怎样的？
域名解析正常
请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。

服务器端配置:
服务器的resov.conf设置的DNS是1.1.1.1和1.0.0.1. 服务器域名解析正常

说明一个情况：
系统设置http代理，通过chrome地址栏使用搜索功能的时候，chrome会发送http://<punycode编码的搜索内容>/的连接请求到代理，<punycode编码的搜索内容>显然是个不合法的域名，会产生invalid domain name警告。

你需要确认你描述的invalid domain name警告是否是因此产生的。
另外我描述的这个场景是不影响正常使用的。

附该情况下的客户端log:

KirbyKFC · 2020-03-03T02:01:32Z

这种情况不需要解决。你应该使用其他工具（nslookup等）检查域名解析问题，并贴出其他部分的日志，因为问题不一定出在域名解析上。

y11022053 · 2020-03-12T12:24:23Z

插个眼，我遇到的问题也是如此，日志出现一些莫名其妙字符串的域名，然后就报错invalid domain name，也同样是在chrome的地址栏进行直接关键字搜索，请问如何避免呢？

fbion · 2020-03-12T12:40:05Z

chrome
mark

bilibilistack · 2020-05-12T02:28:05Z

同样的问题，有这样的log
在chrome地址里面直接搜索时候，有概率会出现这样的问题。出现后大概过1分钟才能恢复网络
WS+TLS
服务端log：
v2ray.com/core/proxy/freedom: failed to get IP address for domain zhong > v2ray.com/core/app/dns: invalid domain name
服务端dns设置的是8.8.4.4
客户端全局，log：

Invalid domain name will be reported when the domain name is indeed invalid, and they are [info], which doesn't at all means an error.

@azazjjyjjy yours seems to be a separate issue and related to mux. try turn it off as a workaround and use a separate issue.
