Bug Description

阿里云作为公网服务器，使用frp对内网的http服务进行代理，然后在阿里服务器上使用NPM根据域名进行流量转发。
阿里云frps配置

......
vhostHttpPort = 1111
......

内网frpc配置

[[proxies]]
name = "gettint-start"
type = "http"
localPort = 3000
customDomains = ["my.domain.xyz"]

使用NPM将流量转发到阿里云服务器的公网ip时，可以使用在公网使用my.domain.xyz访问到内网服务，NPM配置如下：

使用NPM将流量转发到localhost或127.0.0.1时，出现502。

请问如何内内网ip访问呢？
