Openid not working in OSQA hosted on hostgator

I have installed osqa on server hosted on hostgator. Openid is not working at all. When I cli开发者_如何学Pythonck on google under login I get a Page not found (404) error.

What could be the reason for this?

as you noted in your comment on a similar question at http://meta.osqa.net this was a problem with some whitelist issue between Google and hostgator, and apparently they have resolved it. As far as we know, the OSQA openid support works beautifully, and this issue was entirely on the hostgator side.
