Bug Description

I am using ssh gateway of frps to proxy local server to frps. Following is the ssh command I am executing on local machine...

ssh -R :8080:localhost:80 sub.domain.tld -p 2200 http --proxy_name proxy -t 12345678 -u user --custom_domain random

I can confirm that domain dns configuration is correct as random.sub.domain.tld is replying frp's default 404 error while accessing random proxy. Otherwise, that would trigger my web-server's default 404 error file. When I try to access the url, I am getting following error in frps log file

[httputil/reverseproxy.go:486] do http proxy request [host: random.sub.domain.tld:8080] error: no route found: random.sub.domain.tld:8080 /

And I am not getting any traffic on web server of local machine. Server log says that. That means frp is not hitting my local web server which I am trying to proxy onto frps using frpc

Also, is there any exhaustive list of ssh switches frps is using? I couldn't find all the switches in available documentations. Also, --help show very few switches to use with frps

frpc Version

0.61.2

frps Version

Additionally, after starting proxy from client, running curl random.localhost:8080 directly on server also giving same output. Following is the frps log.

2025-04-12 08:47:41.410 [W] [httputil/reverseproxy.go:486] do http proxy request [host: test-http.localhost:8080] error: no route found: test-http.localhost /

Using same config via frpc client works well and that can serve web file.
