ssl - How to setup secure tunnel to allow a client to communicate to a websocket? -

-

i need allow client connect websocket on server 10.0.4.160. 10.0.4.160 server not have ssl installed on have websocket running on port 8080.

i need setup secure tunnel allow client connect websocket.

i installed stunnel on windows server 2008 r2, , changed stunnel.conf file loke 

[websockets] accept = 8443 connect = 8080 verify = 2 cafile = ca-certs.pem client = yes

i expecting connect server on port 8433 , stunnel allow connection connect port 8080

this code use in client's console "of course, console on pc on internal network"

var conn = new websocket('wss://10.0.4.160:8443'); conn.onopen = function(e) {     console.log("connection established!"); };  conn.onmessage = function(e) {     console.log(e.data); };

while on server open command line , execute telnet localhost 8080

i command line , when fire code above console see in server's command line

enter image description here

but few seconds later error in console

websocket connection 'wss://10.0.4.160:8443/' failed: error in connection establishment: net::err_timed_out

if try send command using conn.sent('hello') error

vm289:2 uncaught domexception: failed execute 'send' on 'websocket': still in connecting state.     @ error (native)     @ <anonymous>:2:6     @ object.injectedscript._evaluateon (<anonymous>:905:140)     @ object.injectedscript._evaluateandwrap (<anonymous>:838:34)     @ object.injectedscript.evaluate (<anonymous>:694:21)

additionally, tried turn on debugging in strunnel adding debug = 7

this got in stunnel console. don't understand wrong logs show client connected can't send messages client server
