Does fasthttp.Client has TLSHandshakeTimeout or smth like that internally?

Take a look at tls.DialWithDialer, I think that should be handled by fasthttp.HostClient

[moredure]

probably smth like that

func dialAddr(addr string, dial DialFunc, dialDualStack, isTLS bool, tlsConfig *tls.Config) (net.Conn, error) {
	if dial == nil {
		if dialDualStack {
			dial = DialDualStack
		} else {
			dial = Dial
		}
		addr = addMissingPort(addr, isTLS)
	}
	conn, err := dial(addr)
	if err != nil {
		return nil, err
	}
	if conn == nil {
		panic("BUG: DialFunc returned (nil, nil)")
	}
	if isTLS {
		timeout := 5 * time.Second // make configurable

		var errChannel chan error

		errChannel = make(chan error, 2)
		time.AfterFunc(timeout, func() {
			errChannel <- timeoutError{}
		})

		colonPos := strings.LastIndex(addr, ":")
		if colonPos == -1 {
			colonPos = len(addr)
		}
		hostname := addr[:colonPos]
		// If no ServerName is set, infer the ServerName
		// from the hostname we're connecting to.
		if config.ServerName == "" {
			// Make a copy to avoid polluting argument or default.
			c := tlsConfig.Clone()
			c.ServerName = hostname
			tlsConfig = c
		}

		conn := tls.Client(rawConn, tlsConfig)

		go func() {
			errChannel <- conn.Handshake()
		}()

		err = <-errChannel
		if err != nil {
			rawConn.Close()
			return nil, err
		}
	}
	return conn, nil
}

Smth like prometheus/prometheus#5394, but in fasthttp

Fixed in #631
