Running Apache v2.4, PHP v5.6 w/ php-fpm, on CentOS 7

So I'm trying to get wss working with stunnel & Ratchet. I've got Ratchet's Hello World (http://socketo.me/docs/hello-world) working successfully with the test code on non-ssl at port 8080. I can telnet from the same machine, as well as telnet from a a different machine.

Through reading, I know that ratchet doesn't support ssl connections, but does by wrapping the communications with stunnel, so I setup stunnel with an appropriate cert listening on port 8443, which appears to be working (as evidenced by the log file).

When I try to make a connection using wss from Firefox's scratchpad, I get the following error: Firefox can't establish a connection to the server at wss://testserver.testdomain.com:8443 I can see the connection being created through the various log files, however somewhere along the line communications is failing since I can't create a solid wss connection. Any ideas on what I'm missing or where I'm screwing up? Log/code below

Scratchpad Code

var conn = new WebSocket('wss://testserver.testdomain.com:8443');
conn.onopen = function(e) {
    console.log("Connection established!");
};

conn.onmessage = function(e) {
    console.log(e.data);
};

Stunnel config:

cert = /etc/httpd/ssl/ov_wildcard.pem

[hublistener]
accept = 8443
connect = 8080

Stunnel log:

I have a Ratchet WebSocket running on my own machine and am also using Apache2.4 To make it work over SSL I did:

Proxy pass the socket

inside (/etc/apache2/)apache2.conf I added

    //added for the websocket over SSL
    ProxyPass /wss/ ws://alpha.example.com:8080/

this passes my websocket running on port 8080 to wss://alpha.example.com/wss/

to make sure your stunnel config is correct, this is what I did inside of (/etc/stunnel/)stunnel.conf

cert = /etc/letsencrypt/live/www.example.com/cert.pem
key = /etc/letsencrypt/live/www.example.com/privkey.pem
[wss]
accept = 8082
connect = 8080

REMINDER: change the paths to the keys I used to thee paths your keys are using.

inside the PHP file that starts my server I user port 8080 as in the ratchet example

$webSock->listen(8080, '0.0.0.0'); // Binding to 0.0.0.0 means remotes can connect
