Bug Description

toml格式,网址a.打码会被302到网址b.打码
别的全部没动,只换了配置文件
nginx,服务器等全部没任何变动
去掉transport.proxyProtocolVersion = "v2"正常

挂到alist时则会400,同样去掉transport.proxyProtocolVersion = "v2"正常

挂python-flask会404,同样去掉transport.proxyProtocolVersion = "v2"正常(绝对没有打错字,frpc也显示 start proxy success")

frpc Version

0.53

frps Version

0.53

System Architecture

frps:linux/amd64 frpc: windows/amd64

Configurations

[[proxies]]
name = "a"
type = "http"
localPort = 80
customDomains = ["a.打码.top"]
transport.proxyProtocolVersion = "v2"

[[proxies]]
name = "b"
type = "http"
localPort = 80
customDomains = ["b.打码.xyz"]
transport.proxyProtocolVersion = "v2"

nginx配置:

谢谢你的回复。
是的只能这样。但我需要真实IP地址传回。
我试了nginx和jellyfin的SSL，都不行。

不要在http使用transport.proxyProtocolVersion = "v2"
仅在https中使用...别的不清楚,
截图可以参考

我只有https站点，但也遇到了这个问题，edge报错说证书为空。很奇怪。

在局域网内检查有没有证书问题

在局域网内检查有没有证书问题

没有证书问题。
局域网用内网地址访问需要跳过证书检查，如果把域名设到hosts文件就能正常访问。
外网访问，去掉这行就好了。
