I'm using Chrome 25.0.1364.172 m and on every StackOverflow page I'm logging the following JavaScript console error:

WebSocket connection to 'ws://sockets.ny.stackexchange.com/' failed:
    Unexpected response code: 502

WebSocket connection error

Working fine here. What are the results of this test for you? All green? – Shadow Wizard Mar 20 '13 at 15:18
    
All green apart from WebSockets port 80. I guess this is an issue on my end then! – James Donnelly Mar 20 '13 at 15:21
    
Yeah, exactly like Geoff just said. – Shadow Wizard Mar 20 '13 at 15:21

What this is telling you is that you're traffic is being intercepted by a proxy further up the chain. Usually this is the result of using a mobile connection of some sort. You can verify your web socket support here:

If you see that web socket support is available on port 80 it will work properly. If not sadly you're out of luck.

No way for you for a silent fallback though? – Shadow Wizard Mar 20 '13 at 15:21
    
Just commented on @ShaWizDowArd's comment on the original question - no, port 80 isn't green for me. Looks like this is an issue on my end, sorry for any confusion! – James Donnelly Mar 20 '13 at 15:22
    
@ShaWizDowArd Writing to the console is pretty "silent", that's where you want errors the user doesn't need to care about; displaying a big error banner on the page would be annoying – Michael Mrozek Mar 20 '13 at 15:34
    
@Michael doesn't look like console.write in action, rather unhandled client side exceptions, plus no live updates as result. On browsers not supporting web sockets I'm almost sure I saw fallback to the old mechanism using plain AJAX. – Shadow Wizard Mar 20 '13 at 15:46
    
@ShaWizDowArd the standard heartbeat code when editing answers etc still exists; the rest isn't a case of "fallback" - the live updates is entirely supplemental to the standard UI. Nothing was moved exclusively to there - it was all new features. – Marc Gravell Mar 20 '13 at 16:07

@Marc what about inbox new items notification? I'm almost sure it worked in IE9 which doesn't support web sockets. – Shadow Wizard Mar 20 '13 at 16:10
    
@ShaWizDowArd I am having the same problem for a quite while (In all browsers). It was not happening before. I think it started after installing some important softwares. How to make the proxy not to intercept the traffic? any link? – Mr_Green Aug 22 '13 at 8:59
