TLS handshake hangs and blocks forever

[dannin]

Hi, I logged the following bug against golang.
Not sure if this is actually a symptom from gorilla websocket:
golang/go#17708

Please provide more information. Show the Dialer that you are using. What software is running on the server? Can you connect to the server with a different client (a browser for example)?

Basically it looks like this:
d := websocket.Dialer{
ReadBufferSize: 1024,
WriteBufferSize: 1024,
NetDial: func(network, addr string) (net.Conn, error) {
const timeout = 30 * time.Second
return net.DialTimeout(network, serverAddr, timeout)
},
TLSClientConfig: tlsConfig,
}

ws, _, err = d.Dial(u.String(), wsHeaders)

It also works most of the time. Just when the server goes down intermittenly or theres dns resolution error, sometimes around that time it hangs

@garyburd Any idea? Does that look right? I return a net.Conn with a timeout via the NetDial
