I'm trying to use Slack but I cannot get it to work in Chrome or Firefox. I get a connection error. I use their help test and I get failures on the websockets.
I don't have the same issues when using IE.
I'm behind a work network and both browsers are using the same LAN settings. When I go into LAN settings, the only thing ticked is Use automatic configuration script
and there's a url in there.
Why are the web sockets not an issue in IE and how would I stop them being an issue in other browsers?
Info: Here's some information on browser versions. Chrome: 52.02743.116 IE: 11.0.9600
When going to http://www.websocketstest.com I get the following:
IE: Websockets supported - Yes
HTTP Proxy - Yes
Port 80 - Disconnected
Port 443 - Connected
Port 8080 - Disconnected
Port 443 SSL - Connected
Chrome: Websockets supported - Yes
HTTP Proxy - Yes
All ports disconnected
Tried to connect to slack via http
and wss
as recommended in the comments but it just reverts to https
.
Thanks
well, modern versions of Chrome and FF both support websockets: https://en.wikipedia.org/wiki/WebSocket#Browser_implementation

IE didn't support websockets until late versions of IE10. it could be that slack falls back to a different mechanism on this version that is compatible with your work environment network. Perhaps provide your browser versions you've tried in the question. Some proxy servers are transparent and work fine with WebSocket; others will prevent WebSocket from working correctly, causing the connection to fail. In the off chance you're visiting slack over http://, I'd suggest trying https and wss://, you may trigger different rules, and websocket traffic may flow. – init_js – 2016-09-06T06:21:40.337
