No HTTP(S) traffic goes through

[marcinjahn]

I run the app on my Windows host. I configured Firefox (with FoxyProxy) to connect through that Windows host (SOCKS5). Here's what I see when I try to access https://www.google.com on my Linux host (via Firefox):

Here's the config of ShinySocks:

; Example configuration file.

interfaces {
    interface {
		; Use to listen on all interfaces
		; hostname "0.0.0.0"
	
		; Use for testing on localhost
        hostname "0.0.0.0"
        port 1080
    }
}


system {
    ; Number of io-threads
    io-threads 4
}

log {
    file "shinysocks_%5N.log"
}

I have only modified the hostname to be 0.0.0.0 from the default 127.0.0.1, because I wanted to be able to connect to the proxy from the external host in my LAN.

Here're the logs of ShinySocks on my Windows host:

What's wrong? Why I cannot browser the web via the ShinySocks proxy?

I'll have to take a closer look at this.

This does not appear to be a proxy issue, it appears to be an HSTS issue. https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security

Your browser has essentially cached a trusted configuration for google.com and is not connecting because the identity has changed due to the proxy. The easiest workaround is to use a browser that does not have the cached google.com HSTS values: an incognito/private session or a separate browser should do the trick.
