problem initializing DropboxClient instance

Hi all,

I could achieve file upload from Web API. I get the posted file, and I could upload it to dropbox and get shared URL of the upped file.

However, deploying the app to Azure, I get an exception when creating the DropboxClient object, and all information is: 

ErrorMessage: "shared_link_access_denied/"

ErrorResponse is a SharedLinkError.SharedLinkAccessDenied

Code is:

                    try
                    {
                        dropBoxClient = new DropboxClient(s, new DropboxClientConfig("Forecast5"));
                        remoteFilePath = String.Format("{0}/logo.jpg", formData["id"]);
                        var result = await dropBoxClient.Files.UploadAsync(remoteFilePath, WriteMode.Overwrite.Instance, body: fileStream);
                    }

No idea and what to try. Anyone with a suggestion or idea?

Thanks in advance!!
