RedirAddr behaves quite odd when BindAddr is changed to "non-default" ports ...

[Cebeerre]

Hi !

First of all let me thank @cbeuw and the rest of contributors for this nice piece of sofware ... really awesome !

I'm happily running a setup where traffic goes through Caddy2 running on Docker to be proxied to a Cloak instance running on top of an OpenWRT router where my Wireguard instances live. This setup is working fine without isues using the CDN Transport.

The thing is that ck-server is running on port 1081 on the OpenWRT and even though the plugable thing works perfectly, if I try to connect with a browser to the caddy2 vhost that proxies to the 1081 cloack instance, ck-server actually tries to redirect to the RedirAddr but forcing/using the 1081 port as per the logs:

Wed Oct 18 15:37:36 2023 daemon.err ck-server[13685]: time="2023-10-18T13:37:36Z" level=error msg="Making connection to redirection server: dial tcp 142.250.200.99:1081: connect: connection timed out"

Is this something really expected ?

My server.json looks like this:

{
    "ProxyBook": {
        "wireguard": [
            "udp",
            "127.0.0.1:3478"
        ]
    },
    "BindAddr": [
        ":1081"
    ],
    "BypassUID": [
        "xxxxxxx"
    ],
    "RedirAddr": "google.es",
    "PrivateKey": "xxxxxxx"
}

Many thanks !!

I ran into this too. The solution is to provide the port with the address:

"RedirAddr": "google.es", to "RedirAddr": "google.es:443",
