couldn't upgrade websocket

[ardawan]

I'm using it on my local machine and servers are separated by docker.

I'm getting errors from the websocketproxy.

this is the log

params := mux.Vars(res) 
url, _ := url.Parse("ws://14.14.0.1:7039/ws/" + params["token"])
proxy := websocketproxy.NewProxy(url)
proxy.ServeHTTP(w, res)
}

I ran into the same issue as well. I was able to fix it by making the following tweak to the source code:

    upgrader.CheckOrigin = func(r *http.Request) bool {
        // Allow any origin to connect
        return true
    }
