Hi,

I hope someone can help me here as I have been stuck for the past 3 days.

I need to allow a client to connect to a websocket running on server 10.0.4.160 on port 8080.

I need to setup a secure tunnel to allow the client to connect to the websocket via port 58443.

I installed the latest version of stunnel on my windows Server 2008 R2. Then I changed my stunnel.conf file to look like this

[websockets]

client = yes

accept = 58443

connect = 8080

verify = 2

checkIP = 10.0.4.195

CAfile = ca-certs.pem

debug = 7

OCSPaia = yes

##The rest have been removed

I am expecting to open a connection from the user’s console on port 58443 and the stunnel will allow the client to connect to port 8080

This is the code that I use in the client's console "Of course, the console is on a PC that is on my internal network"

var conn = new WebSocket('wss://10.0.4.160:58443');

conn.onopen = function(e) {

    console.log("Connection established!");

};

conn.onmessage = function(e) {

    console.log(e.data);

};

While on the server, I open up a command line and I execute this telnet localhost 8080 to open up a command line where I can see the incoming request. As soon as I fire the code above from a client javascript’s console I see this in the server's command line

But few seconds later I get this error in the client’s console

WebSocket connection to 'wss://10.0.4.160:58443/' failed: Error in connection establishment: net::ERR_TIMED_OUT

If I try to send a command using conn.sent('Hello') I get this error

VM289:2 Uncaught DOMException: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.

    at Object.InjectedScript._evaluateAndWrap (<anonymous>:838:34)
    at Object.InjectedScript.evaluate (<anonymous>:694:21)

Additionally, I tried to turn on debugging in strunnel by adding debug = 7 to the config file

This is what I got in the stunnel console. I don't understand what is wrong as the logs show that the client is connected but I can't send messages from the client to the server

What am I doing wrong here? How come the connection keeps failing?
