Websockets not working

I found nifty little webapp based on the TV show Jeopardy. It uses websockets which I can't seem to get running.

The code for the game can be found here: https://github.com/tpavlek/Jeopardy

I'm pretty sure I have all the mods I need enabled, here's a list of installed ones.

My apache conf file is this:

<VirtualHost *:80>
  DocumentRoot /home/user/Jeopardy/client/
  ServerName jeopardy.url.tld

  <Directory /home/user/Jeopardy/client/>
     Options +FollowSymlinks
     AllowOverride All
     Require all granted
  </Directory>
    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

  RewriteEngine on
    RewriteCond %{HTTP:Upgrade} =websocket
    RewriteRule /(.*) ws://localhost:9001/$1 [P,L]

  ProxyPass /ws ws://localhost:9001/
  ProxyPreserveHost On
  ProxyVia full

  <Proxy>
    Order deny,allow
    Allow from all
  </Proxy>

  ErrorLog ${APACHE_LOG_DIR}/jeopardy-error.log
  CustomLog ${APACHE_LOG_DIR}/jeopardy-access.log combined

</VirtualHost>

Code (markup):

When I connect to the site on port 80 the site loads up, I can select Player 1, 2, or 3 and the game board loads. It's just at this point where WebSockets are needed that it fails.

I'd love to get this going to offer an activity for my Scout Troop while we are stuck holding virtual meetings only.

Thanks,

 

Can you post the link to the live project if you have it online?
Also, did you run the server.php file?
