Question

Here’s the issue, on Firefox 15 WebSocket like the echo test will work on my computer at home but not at work. I was under the impression that WebSocket was designed to work with existing proxy settings.

Also its worth noting that at work the echo test is successful on Chrome but not Firefox, and that both browser are configured to use the system settings.

Firebug gives me the following error:

Firefox can’t establish a connection to the server at
wss://echo.websocket.org/?encoding=text.

What could be the cause?

Answer 1

Reasons in this case (secure WS on standard port 443) could be:

• proxy auth required
• invalid (i.e. self-signed) TLS cert
