cloud dropbox

I am using the dropbox demo and followed the steps for Chromium. When I run the demo and click the connect button I get this error


Error (400)

It seems the app you were using submitted a bad request. If
you would like to report this error to the app's developer, include the
information below.


More details for developers

Invalid redirect_uri. It must exactly match one of the redirect URIs you've pre-configured for your app (including the path).


Any help would be appreciated.


Thanks

I'm not sure what you mean with  "followed the steps for chromium" in relationship to the TMS VCL Cloud Pack as this one never utilized Chromium.
Also, in case this refers to TMS FMX Cloud Pack, since XE8 Chromium has also been deprecated and you can use the built XE8 TWebBrowser instead (which is used inside the authentication/authorization dialog). If you use XE8 or newer, do you also use the latest version of the TMS FMX Cloud Pack?
