Bug Description

今天突然发现通过内网去访问同属于内网的两台Nginx服务器都访问不了了，网页打不开，但是在外网访问正常，查看服务器/var/log/nginx/error日志发现：
2022/03/17 17:58:20 [error] 75479#0: *660 broken header: "^V^C^A^B^@^A^@^Aü^C^C¾¯oHPñÂf <98>2ïj<96>^BÁ^B^O«6^Y<92>~Î"sJ£qØ^HE NÖ2<9a><9e><92>ñ½t<8e><93>C?<81><9f>^^.x<99>&j²^KÏõÂ<83>®ç1<8f>á^@ ºº^S^A^S^B^S^CÀ+À/À,À0Ì©Ì¨À^SÀ^T^@<9c>^@<9d>^@/" while reading PROXY protocol, client: 192.168.1.7, server: 0.0.0.0:443

192.168.1.7是公司内网客户端IP。

在Nginx配置文件里取消以下相关设置后正常：
listen 443 ssl http2 proxy_protocol;
real_ip_header proxy_protocol;
set_real_ip_from 192.168.1.5/32; // FRP Server IP

这几天没做什么改动，只是将FRP从0.38.1升级到0.4,而且内网访问不走frp，不知道为什么会这样？理

frpc Version

0.40

frps Version

0.40

System Architecture

linux/amd64

Configurations

listen 443 ssl http2 proxy_protocol;
real_ip_header proxy_protocol;
set_real_ip_from 192.168.1.5/32; // FRP Client IP

经过多次测试，在内网nginx服务器上，增加另外一个端口解决：
listen 8443 ssl http2 proxy_protocol;

然后在frpc.ini上配置：
[www]
type = https
local_port = 8443
local_ip = 192.168.1.10
custom_domains = xxx.domain.com
proxy_protocol_version = v2
