Connection error

[Reem]

Hi,
I developed a website using c# which get user steps from Fitbit. And it was working fine on my local host, but when I uploaded the files on the server on live, I got error. it showed the Fitbit site and once I login to give the auth to the application, it gives this error:
Fitbit
The app you're trying to connect did not provide valid information to Fitbit. Please report this issue to them.

Developer information: invalid_request - Invalid redirect_uri parameter value

I think I have a problem with callback url which is stated as
Http://myserver.edu.au/main.aspx
Any help please?

The value of the redirect_uri in the authorization page URL must match a URI listed in your app settings on https://dev.fitbit.com/apps

Thanks for your reply, appreciated. Yes I copy the url of the main page which is http://liveservername.edu.au/main.aspx
And paste it in the callback url in my application setting but still not working, is this what you mean that I should do?

But are you specifying the same redirect URL in the redirect_uri parameter on the Authorization page?
