ssl only: Error reading data from socket: Not connected

[dumshi]

Chrome gives this error:
WebSocket connection to 'wss://server.somewhere:8000/echo' failed: WebSocket opening handshake was canceled

I get this error when testing server_ssl.php in cli:

root@m1048:/var/www/html/Wrench-master/examples# php -q server_ssl.php

This does not happen in normal plain "server.php" test, only in ssl.

Ok,
After few testing and reading. I also went to https://server.somewhere:8000 port and accepted the self-signed cert.
I have to leave that window OPEN for the next window with https://server.somewhere/ with wss:// to work.

Also started to notice weird things when I send a chat msg.

WebSocket - status 0
Welcome - status 1
Sent: asdf
Sent: asdf
Received: asdf
Sent: asdfasdf
Received: asdf
Sent: a
Received: asdfasdf
Sent: a
Received: a
Sent: a
Received: a
Sent: asdf
Received: a
Sent: a
Received: asdf
Sent: asdf
Received: a

Notice how the first msg was never "sent" (hence did not receive immediately).
Asap, i sent the 2nd msg, the first msg bounced back (assuming when i sent the 2nd msg, the first was went to server).
Is there a Queue system of some kind in SSL mode ??

What is going on?

I had same problem with my other project, and so I decided to download a fresh new Wrench copy.
And I am seeing similar things.

Please someone explain.

Help!!!

I am using helper for the workaround.
If anyone knows how to fix this, please let me know.
Thanks in advance.

Workaround:
*WebSocket helpers
* Checks websocket state before sending.
*/
this.waitForConnection = function (callback, interval) {
if (websocket.readyState === 1) {
callback();
} else {
var that = this;
setTimeout(function () {
that.waitForConnection(callback);
}, interval);
}
};
function send(message, callback) {
this.waitForConnection(function () {

        websocket.send(message);
            websocket.send(""); //send empty msg after your real msg.

        if (typeof callback !== 'undefined') {
          callback();
        }
    }, 1000);
};

Hi!
I'm not sure that this problem is related to server hang, but could you check this fix

[emadruida]

It looks like Issue #61 to me. See if this can help you.

@Alarmfifa It did not look like anything to do with Large Messages, as I was only send "asdf". But thank you for your reply.

@emadruida Your fix did the trick.

Thank you both for quick reply.

@Alarmfifa It did not look like anything to do with Large Messages, as I was only send "asdf". But thank you for your reply.

"Large message" isn't only for message data. It is about full http message with it's header (cookies for example).
I debugged with small message, but with a big header in one browser. So, my problem is a bit difficult for reproducing.

The fix mentioned by @emadruida has been merged into v2.0.8 (and v3.0.x-dev) (9dd8175) - let me know if that fixes things
