title: WebSocket connection to 'wss://...' failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED
body: <p>I have a pretty stange error:</p>
  
  <p>I was trying to test live chat made on websockets, but when the scripts loaded, I get this message in developer tools window:
  "WebSocket connection to 'wss://chat.mywebsite.com:80/testuser@wr94@34@0: Error in connection establishment: net::ERR_CONNECTION_CLOSED"</p>
  
  <p>The error message in developer tools sends me to this line of code:
  wrc_socket = new WebSocket(_wsServerUrl+'/'+login+'@wr94@'+_id+'@'+_userType);</p>
  
  <p>I was trying to figure out this issue with chat developers, and we found, that this issue is only happening on my computer where I'm working.</p>
  
  <p>Same browsers, same network, same OS - I have the issue, everyone else don't have it. Apperently, something installed on my computer that blocks wss connections. But I can't figure out what exactly. Tryed disabling antivirus and windows firewall, no result.</p>
  
  <p>I've tested with chrome, firefox and opera (all letest versions). When installed on my computer - they reproduce this error, when installed on collegue's computer (he sist just next to me in the same office) error not happening.</p>
  
  <p>Also, I've tried this on my home computer and got even more strange result: Opera and Firefox reproduse the issue, and Chrome works fine.</p>
  
  <p>Can you give me a hint or a direction to investigate this? I think it's related to certificates stuff, but don't know where to start.</p>
