Figured it out, it was because I had disabled sending the Referer header in Firefox. Not sure why the 404 error code was chosen for "missing Referer header", though...

The referer is required due to some shared internal processing to validate everything is happy between the sites. I have clarified the message the user sees for this scenario.

  • I'm behind a nazi-proxy that strips that header out. Is there a workaround that enables me to use chat? For example, a URL param I can use to specify the stack I'm coming from?

  • @Ranieri you can just go to the "site" tab? for example chat.stackexchange.com/… Jul 26, 2012 at 7:31
  • If I follow your link, I can see the char rooms associated with "bicycles". However, I'm not logged in ("Log In" in header). If i click on a chatroom, I access the chat but I can't participate because I am not logged in. If instead I click "log in" in the header I end up on the chat login page. "Log in with stackexchange" gives me the error "No referer was present - this may be due to a browser setting" (which is due to the naziproxy). Test and help page gives me the all-clear.
